Fields of InvalidHexCharacter

c: charindex: usize

OddLength

[−] Expand description

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

InvalidStringLength

[−] Expand description

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.
