pub extern "rust-intrinsic" fn saturating_sub<T>(a: T, b: T) -> T
🔬 This is a nightly-only experimental API. (
intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
a - b, while saturating at numeric bounds.
The stabilized versions of this intrinsic are available on the integer
primitives via the
saturating_sub method. For example,
