Struct `GeneralPurpose`

pub struct GeneralPurpose { /* private fields */ }

A general-purpose base64 engine.

It uses no vector CPU instructions, so it will work on any system. For a version that uses SIMD where available, see the SIMD engines behind the simd-unsafe feature.
It is reasonably fast (~2-3GiB/s).
It is not constant-time, though, so it is vulnerable to timing side-channel attacks. For loading cryptographic keys, etc, it is suggested to use the forthcoming constant-time implementation.

Implementations

`impl GeneralPurpose`

const fn new(alphabet: &Alphabet, config: GeneralPurposeConfig) -> Self

Create a GeneralPurpose engine from an [Alphabet].

While not very expensive to initialize, ideally these should be cached if the engine will be used repeatedly.
