Struct Ref

Source 
pub struct Ref<Tag>(/* private fields */);
Expand description

A ResourceTag that corresponds to a shared reference to the output value of Tag. Can also be used as an operator on TypeFn implementations.

For example: Ref<Value<T>> implements the following for all 'x, T: 'static:

ⓘ
TypeFn<Output<Lt!['x]> = &'x T> + ResourceTag + TagFor<Lt!['x], Value = &'x T>

Trait Implementations§
