}
Expand description
Errors that can occur while decoding.
Variants§
InvalidByte(usize, u8)
An invalid byte was found in the input. The offset and offending byte are provided.
Padding characters (=
) interspersed in the encoded form are invalid, as they may only
be present as the last 0-2 bytes of input.
This error may also indicate that extraneous trailing input bytes are present, causing otherwise valid padding to no longer be the last bytes of input.
InvalidLength(usize)
The length of the input, as measured in valid base64 symbols, is invalid. There must be 2-4 symbols in the last input quad.
InvalidLastSymbol(usize, u8)
The last non-padding input symbol’s encoded 6 bits have nonzero bits that will be discarded. This is indicative of corrupted or truncated Base64. Unlike DecodeError::InvalidByte, which reports symbols that aren’t in the alphabet, this error is for symbols that are in the alphabet but represent nonsensical encodings.
InvalidPadding
The nature of the padding was not as configured: absent or incorrect when it must be canonical, or present when it must be absent, etc.
