Enum hex::FromHexError

pub enum FromHexError {
    InvalidHexCharacter {
        c: char,
        index: usize,
    },
    OddLength,
    InvalidStringLength,
}

The error type for decoding a hex string into Vec<u8> or [u8; N].

Variants

InvalidHexCharacter

An invalid character was found. Valid ones are: 0...9, a...f or A...F.

Fields of InvalidHexCharacter

c: charindex: usize

OddLength

A hex string's length needs to be even, as two digits correspond to one byte.

InvalidStringLength

If the hex string is decoded into a fixed sized container, such as an array, the hex string's length * 2 has to match the container's length.
