Expand description

Gets an identifier which is globally unique to the specified type. This function will return the same value for a type regardless of whichever crate it is invoked in.

Note that, unlike most intrinsics, this can only be called at compile-time as backends do not have an implementation for it. The only caller (its stable counterpart) wraps this intrinsic call in a `const` block so that backends only see an evaluated constant.

The stabilized version of this intrinsic is `core::any::TypeId::of`.
