### Release Notes

<summary>marshallpierce/rust-base64 (base64)</summary>

### [`v0.22.0`](https://togithub.com/marshallpierce/rust-base64/blob/HEAD/RELEASE-NOTES.md#0220)

[Compare Source](https://togithub.com/marshallpierce/rust-base64/compare/v0.21.7...v0.22.0)

-   `DecodeSliceError::OutputSliceTooSmall` is now conservative rather than precise. That is, the error will only occur if the decoded output *cannot* fit, meaning that `Engine::decode_slice` can now be used with exactly-sized output slices. As part of this, `Engine::internal_decode` now returns `DecodeSliceError` instead of `DecodeError`, but that is not expected to affect any external callers.
-   `DecodeError::InvalidLength` now refers specifically to the *number of valid symbols* being invalid (i.e. `len % 4 == 1`), rather than just the number of input bytes. This avoids confusing scenarios when based on interpretation you could make a case for either `InvalidLength` or `InvalidByte` being appropriate.
-   Decoding is somewhat faster (5-10%)
