Decoding can now either ignore padding, require correct padding, or require no padding. The default is to require correct padding.
The NO_PAD config now requires that padding be absent when decoding.
0.20.0-alpha.1
Breaking changes
Extended the Config concept into the Engine abstraction, allowing the user to pick different encoding / decoding implementations.
What was formerly the only algorithm is now the FastPortable engine, so named because it's portable (works on any CPU) and relatively fast.
This opens the door to a portable constant-time implementation (#153, presumably ConstantTimePortable?) for security-sensitive applications that need side-channel resistance, and CPU-specific SIMD implementations for more speed.
Standard base64 per the RFC is available via DEFAULT_ENGINE. To use different alphabets or other settings (padding, etc), create your own engine instance.
CharacterSet is now Alphabet (per the RFC), and allows creating custom alphabets. The corresponding tables that were previously code-generated are now built dynamically.
Since there are already multiple breaking changes, various functions are renamed to be more consistent and discoverable.
MSRV is now 1.47.0 to allow various things to use const fn.
DecoderReader now owns its inner reader, and can expose it via into_inner(). For symmetry, EncoderWriter can do the same with its writer.
encoded_len is now public so you can size encode buffers precisely.
0.13.1
More precise decode buffer sizing, avoiding unnecessary allocation in decode_config.
