pub struct Ref<'a, T, U>(/* private fields */)
where
T: EncodeLike<U>,
U: Encode;Expand description
Reference wrapper that implement encode like any type that is encoded like its inner type.
§Example
fn foo<T: EncodeLike<u8>>(t: T) -> T {
store_t(Ref::from(&t)); // Store t without moving it, but only using a reference.
t
}
fn store_t<T: EncodeLike<u8>>(t: T) {
