// expected by the Rust code on the other side of the interface. In practice right
// now that means coming from the exact some version of `uniffi` that was used to
// compile the Rust component. The easiest way to ensure this is to bundle the Kotlin
// helpers directly inline like we're doing here.

// * IntegrityCheckingUniffiLib
// And all checksum methods are put into `IntegrityCheckingUniffiLib`

// This template implements a class for working with a Rust struct via a handle
// to the live Rust struct on the other side of the FFI.
//
// There's some subtlety here, because we have to be careful not to operate on a Rust
// struct after it has been dropped, and because we must expose a public API for freeing
// theq Kotlin wrapper object in lieu of reliable finalizers. The core requirements are:
//
//   * Each instance holds an opaque handle to the underlying Rust struct.
//     Method calls need to read this handle from the object's state and pass it in to
//     the Rust FFI.
//
//   * When an instance is no longer needed, its handle should be passed to a
//     special destructor function provided by the Rust FFI, which will drop the
//     underlying Rust struct.
//
//   * Given an instance, calling code is expected to call the special
//     `destroy` method in order to free it after use, either by calling it explicitly
//     or by using a higher-level helper like the `use` method. Failing to do so risks
//     leaking the underlying Rust struct.
//
//   * We can't assume that calling code will do the right thing, and must be prepared
//     to handle Kotlin method calls executing concurrently with or even after a call to
//     `destroy`, and to handle multiple (possibly concurrent!) calls to `destroy`.
//
//   * We must never allow Rust code to operate on the underlying Rust struct after
//     the destructor has been called, and must never call the destructor more than once.
//     Doing so may trigger memory unsafety.
//
//   * To mitigate many of the risks of leaking memory and use-after-free unsafety, a `Cleaner`
//     is implemented to call the destructor when the Kotlin object becomes unreachable.
//     This is done in a background thread. This is not a panacea, and client code should be aware that
//      1. the thread may starve if some there are objects that have poorly performing
//     `drop` methods or do significant work in their `drop` methods.
//      2. the thread is shared across the whole library. This can be tuned by using `android_cleaner = true`,
//         or `android = true` in the [`kotlin` section of the `uniffi.toml` file](https://mozilla.github.io/uniffi-rs/kotlin/configuration.html).
//
// If we try to implement this with mutual exclusion on access to the handle, there is the
// possibility of a race between a method call and a concurrent call to `destroy`:
//
//    * Thread A starts a method call, reads the value of the handle, but is interrupted
//      before it can pass the handle over the FFI to Rust.
//    * Thread B calls `destroy` and frees the underlying Rust struct.
//    * Thread A resumes, passing the already-read handle value to Rust and triggering
//      a use-after-free.
//
// One possible solution would be to use a `ReadWriteLock`, with each method call taking
// a read lock (and thus allowed to run concurrently) and the special `destroy` method
// taking a write lock (and thus blocking on live method calls). However, we aim not to
// generate methods with any hidden blocking semantics, and a `destroy` method that might
// block if called incorrectly seems to meet that bar.
//
// So, we achieve our goals by giving each instance an associated `AtomicLong` counter to track
// the number of in-flight method calls, and an `AtomicBoolean` flag to indicate whether `destroy`
// has been called. These are updated according to the following rules:
//
//    * The initial value of the counter is 1, indicating a live object with no in-flight calls.
//      The initial value for the flag is false.
//
//    * At the start of each method call, we atomically check the counter.
//      If it is 0 then the underlying Rust struct has already been destroyed and the call is aborted.
//      If it is nonzero them we atomically increment it by 1 and proceed with the method call.
//
//    * At the end of each method call, we atomically decrement and check the counter.
//      If it has reached zero then we destroy the underlying Rust struct.
//
//    * When `destroy` is called, we atomically flip the flag from false to true.
//      If the flag was already true we silently fail.
//      Otherwise we atomically decrement and check the counter.
//      If it has reached zero then we destroy the underlying Rust struct.
//
// Astute readers may observe that this all sounds very similar to the way that Rust's `Arc<T>` works,
// and indeed it is, with the addition of a flag to guard against multiple calls to `destroy`.
//
// The overall effect is that the underlying Rust struct is destroyed only when `destroy` has been
// called *and* all in-flight method calls have completed, avoiding violating any of the expectations
// of the underlying Rust code.
//
// This makes a cleaner a better alternative to _not_ calling `destroy()` as
// and when the object is finished with, but the abstraction is not perfect: if the Rust object's `drop`
// method is slow, and/or there are many objects to cleanup, and it's on a low end Android device, then the cleaner
// thread may be starved, and the app will leak memory.
//
// In this case, `destroy`ing manually may be a better solution.
//
// The cleaner can live side by side with the manual calling of `destroy`. In the order of responsiveness, uniffi objects
// with Rust peers are reclaimed:
//
// 1. By calling the `destroy` method of the object, which calls `rustObject.free()`. If that doesn't happen:
// 2. When the object becomes unreachable, AND the Cleaner thread gets to call `rustObject.free()`. If the thread is starved then:
// 3. The memory is reclaimed when the process terminates.

//      2. the thread is shared across the whole library. This can be tuned by using `android_cleaner = true`,
//         or `android = true` in the [`kotlin` section of the `uniffi.toml` file](https://mozilla.github.io/uniffi-rs/kotlin/configuration.html).
//
// If we try to implement this with mutual exclusion on access to the handle, there is the
// possibility of a race between a method call and a concurrent call to `destroy`:
//
//    * Thread A starts a method call, reads the value of the handle, but is interrupted
//      before it can pass the handle over the FFI to Rust.
//    * Thread B calls `destroy` and frees the underlying Rust struct.
//    * Thread A resumes, passing the already-read handle value to Rust and triggering
//      a use-after-free.
//
// One possible solution would be to use a `ReadWriteLock`, with each method call taking
// a read lock (and thus allowed to run concurrently) and the special `destroy` method
// taking a write lock (and thus blocking on live method calls). However, we aim not to
// generate methods with any hidden blocking semantics, and a `destroy` method that might
// block if called incorrectly seems to meet that bar.
//
// So, we achieve our goals by giving each instance an associated `AtomicLong` counter to track
// the number of in-flight method calls, and an `AtomicBoolean` flag to indicate whether `destroy`
// has been called. These are updated according to the following rules:
//
//    * The initial value of the counter is 1, indicating a live object with no in-flight calls.
//      The initial value for the flag is false.
//
//    * At the start of each method call, we atomically check the counter.
//      If it is 0 then the underlying Rust struct has already been destroyed and the call is aborted.
//      If it is nonzero them we atomically increment it by 1 and proceed with the method call.
//
//    * At the end of each method call, we atomically decrement and check the counter.
//      If it has reached zero then we destroy the underlying Rust struct.
//
//    * When `destroy` is called, we atomically flip the flag from false to true.
//      If the flag was already true we silently fail.
//      Otherwise we atomically decrement and check the counter.
//      If it has reached zero then we destroy the underlying Rust struct.
//
// Astute readers may observe that this all sounds very similar to the way that Rust's `Arc<T>` works,
// and indeed it is, with the addition of a flag to guard against multiple calls to `destroy`.
//
// The overall effect is that the underlying Rust struct is destroyed only when `destroy` has been
// called *and* all in-flight method calls have completed, avoiding violating any of the expectations
// of the underlying Rust code.
//
// This makes a cleaner a better alternative to _not_ calling `destroy()` as
// and when the object is finished with, but the abstraction is not perfect: if the Rust object's `drop`
// method is slow, and/or there are many objects to cleanup, and it's on a low end Android device, then the cleaner
// thread may be starved, and the app will leak memory.
//
// In this case, `destroy`ing manually may be a better solution.
//
// The cleaner can live side by side with the manual calling of `destroy`. In the order of responsiveness, uniffi objects
// with Rust peers are reclaimed:
//
// 1. By calling the `destroy` method of the object, which calls `rustObject.free()`. If that doesn't happen:
// 2. When the object becomes unreachable, AND the Cleaner thread gets to call `rustObject.free()`. If the thread is starved then:
// 3. The memory is reclaimed when the process terminates.

// This template implements a class for working with a Rust struct via a handle
// to the live Rust struct on the other side of the FFI.
//
// There's some subtlety here, because we have to be careful not to operate on a Rust
// struct after it has been dropped, and because we must expose a public API for freeing
// theq Kotlin wrapper object in lieu of reliable finalizers. The core requirements are:
//
//   * Each instance holds an opaque handle to the underlying Rust struct.
//     Method calls need to read this handle from the object's state and pass it in to
//     the Rust FFI.
//
//   * When an instance is no longer needed, its handle should be passed to a
//     special destructor function provided by the Rust FFI, which will drop the
//     underlying Rust struct.
//
//   * Given an instance, calling code is expected to call the special
//     `destroy` method in order to free it after use, either by calling it explicitly
//     or by using a higher-level helper like the `use` method. Failing to do so risks
//     leaking the underlying Rust struct.
//
//   * We can't assume that calling code will do the right thing, and must be prepared
//     to handle Kotlin method calls executing concurrently with or even after a call to
//     `destroy`, and to handle multiple (possibly concurrent!) calls to `destroy`.
//
//   * We must never allow Rust code to operate on the underlying Rust struct after
//     the destructor has been called, and must never call the destructor more than once.
//     Doing so may trigger memory unsafety.
//
//   * To mitigate many of the risks of leaking memory and use-after-free unsafety, a `Cleaner`
//     is implemented to call the destructor when the Kotlin object becomes unreachable.
//     This is done in a background thread. This is not a panacea, and client code should be aware that
//      1. the thread may starve if some there are objects that have poorly performing
//     `drop` methods or do significant work in their `drop` methods.
//      2. the thread is shared across the whole library. This can be tuned by using `android_cleaner = true`,
