Struct DoubleDeref

Source 
pub struct DoubleDeref<T> { /* private fields */ }
Expand description

A wrapper for a smart pointer that implements Deref and DerefMut by dereferencing the type inside the smart pointer.

This is quite obscure and mostly useful for situations in which we want a wrapper for Box<dyn Deref<Target = T>> that dereferences to T rather than dereferencing to dyn Deref<Target = T>.

This is used internally in MappedSignal and ArcMappedSignal.
