Struct parity_scale_codec::Ref[−][src]

pub struct Ref<'a, T: EncodeLike<U>, U: Encode>(_, _);

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) {
}
