# [−][src]Function core::intrinsics::type_id

    pub unsafe extern "rust-intrinsic" fn type_id<T: ?Sized + 'static>() -> u64

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

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

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.

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