pub struct Index<T, U>(_, _);
Expand description

A slot in a type’s “extra data” structure.

It is parameterized over the type containing the extra data as well as the type of the data in the slot.

Implementations

Creates an Index from a raw integer index.

Safety

The caller must ensure that the index correctly maps to a U value stored in a T.
