Struct bytecodec::combinator::AndThen
[−]
[src]
pub struct AndThen<D0, D1, F> { /* fields omitted */ }
Combinator for conditional decoding.
If the first item is successfully decoded,
it will start decoding the second item by using the decoder returned by f
function.
This is created by calling DecodeExt::and_then
method.
