pub const fn type_id<T>() -> TypeIdwhere
T: 'static + ?Sized,
🔬This is a nightly-only experimental API. (
core_intrinsics
)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
.
