Enum frame_metadata::DecodeDifferent

source · [−]

pub enum DecodeDifferent<B, O> where
    B: 'static,
    O: 'static,  {
    Encode(B),
    Decoded(O),
}

Expand description

A type that decodes to a different type than it encodes. The user needs to make sure that both types use the same encoding.

For example a &'static [ &'static str ] can be decoded to a Vec<String>.

Variants

`Encode(B)`

`Decoded(O)`
