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

    pub unsafe extern "rust-intrinsic" fn saturating_sub<T: Copy>(a: T, b: T) -> T

🔬 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

Expand description

Computes `a - b`, saturating at numeric bounds.

The stabilized versions of this intrinsic are available on the integer primitives via the `saturating_sub` method. For example, `u32::saturating_sub`
