Core encoder/decoder functions for a particular Base64 alphabet.

Required Associated Constants

const BASE: u8

First character in this Base64 alphabet.

const DECODER: &'static [DecodeStep]

Decoder passes

const ENCODER: &'static [EncodeStep]

Encoder passes

const PADDED: bool

Is this encoding padded?

Required Associated Types

type Unpadded: Alphabet

Unpadded equivalent of this alphabet.

For alphabets that are unpadded to begin with, this should be Self.

Provided Methods

fn decode_3bytes(src: &[u8], dst: &mut [u8]) -> i16

Decode 3 bytes of a Base64 message.

fn decode_6bits(src: u8) -> i16

Decode 6-bits of a Base64 message.

fn encode_3bytes(src: &[u8], dst: &mut [u8])

Encode 3-bytes of a Base64 message.

fn encode_6bits(src: i16) -> u8

Encode 6-bits of a Base64 message.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
