Struct lrs::marker::PhantomData

A dummy type for unused type parameters.

Syntax

struct PhantomData<T>
    where T: ?Sized,

Trait implementations

Name	Description
Clone	Objects that can be duplicated.
Copy	Objects that can safely be copied via `memcpy`.
Eq	Objects that implement the binary `==` and `!=` operators.

Remarks

Normally, all type parameters have to be used in some way. If a type has type parameters that are not used directly in the type definition, it has to use this object instead:

struct X<T> {
    _dummy: PhantomData<T>,
}
