Function type_id 

pub const fn type_id<T: ?Sized>() -> TypeId

🔬This is a nightly-only experimental API. (core_intrinsics)

This item is validated for IEC 61508 (SIL 2) and ISO 26262 (ASIL B).

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.
