Enum frame_support::dispatch::DecodeDifferent

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

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
