Enum InjectiveDecode 

pub enum InjectiveDecode<T, const N: usize> {
    Valid(T),
    Invalid([u8; N]),
}

T wrapper with a constant encoded length (N) and an injective decode implementation.

Note that the decode implementation will not be injective if T::decode accepts non-canonical encodings.

Variants

Valid(T)

Invalid([u8; N])
