This is enforced using compile-time monomorphization errors. ([#1115])- Size of `EagerBuffer` is equal to buffer size, while previously it was equal  to buffer size plus one byte ([#823])- Edition changed to 2024 and MSRV bumped to 1.85 ([#1149])### Removed- `EagerBuffer::set_data` method. Use the `ReadBuffer` type instead.

([#671])- Added buffer kind type parameter to `BlockBuffer`, respective marker types, and type aliases. ([#671])- Various `BlockBuffer` method changes. ([#671])### Removed- `pad_with` method and dependency on `block-padding`. ([#671])[#671]: https://github.com/RustCrypto/utils/pull/671## 0.10.0 (2020-12-08)### Changed- Rename `input_block(s)` methods to `digest_block(s)`. ([#113])- Upgrade the `block-padding` dependency to v0.3. ([#113])### Added- `par_xor_data`, `xor_data`, and `set_data` methods. ([#113])### Removed- The `input_lazy` method.
