Trait RefDecodable

Source
pub trait RefDecodable<'tcx, D>
where D: TyDecoder,
{ // Required method fn decode(d: &mut D) -> &'tcx Self; }
Expand description

Trait for decoding to a reference.

This is a separate trait from Decodable so that we can implement it for upstream types, such as FxHashSet.

The TyDecodable derive macro will use this trait for fields that are references (and don’t use a type alias to hide that).

Decodable can still be implemented in cases where Decodable is required by a trait bound.

Required Methods§

Source

fn decode(d: &mut D) -> &'tcx Self

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
