3/// A trait implemented for types which can be visited by reference.
4///
5/// This behaves the same as [`DecodeUnsized`], but implicitly hints that the
6/// caller is after bytes.
7///
8/// This is used for types like `[u8]` which are unsized, and might require
9/// internal allocating to properly decode. Simply using the `Decode`
10/// implementation would restrict it to only be used through `&'de [u8]` which
11/// would demand an exact reference to data from the decoded source.
12///
