Documentation for the Digest trait, including its required methods, dyn compatibility, and implementors.

```APIDOC
## Trait Digest

### Description
Convenience wrapper trait covering functionality of cryptographic hash functions with fixed output size. This trait wraps `Update`, `FixedOutput`, `Default`, and `HashMarker` traits and provides additional convenience methods.

### Required Methods

#### `fn new() -> Self`
Create new hasher instance.

#### `fn new_with_prefix(data: impl AsRef<[u8]>) -> Self`
Create new hasher instance which has processed the provided data.

#### `fn update(&mut self, data: impl AsRef<[u8]>)`
Process data, updating the internal state.

#### `fn chain_update(self, data: impl AsRef<[u8]>) -> Self`
Process input data in a chained manner.

#### `fn finalize(self) -> Array<u8, Self::OutputSize>`
Retrieve result and consume hasher instance.

#### `fn finalize_into(self, out: &mut Array<u8, Self::OutputSize>)`
Write result into provided array and consume the hasher instance.

#### `fn finalize_reset(&mut self) -> Array<u8, Self::OutputSize>` where `Self: FixedOutputReset`
Retrieve result and reset hasher instance.

#### `fn finalize_into_reset(&mut self, out: &mut Array<u8, Self::OutputSize>)` where `Self: FixedOutputReset`
Write result into provided array and reset the hasher instance.

#### `fn reset(&mut self)` where `Self: Reset`
Reset hasher instance to its initial state.

#### `fn output_size() -> usize`
Get output size of the hasher.

#### `fn digest(data: impl AsRef<[u8]>) -> Array<u8, Self::OutputSize>`
Compute hash of `data`.

### Dyn Compatibility
This trait is **not** dyn compatible. In older versions of Rust, dyn compatibility was called "object safety".

### Implementors
`impl<D> Digest for D` where `D: FixedOutput + Default + Update + HashMarker`.
