Enum frame_support::dispatch::DecodeDifferent [−][src]
pub enum DecodeDifferent<B, O> where
O: 'static,
B: '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>
.
