std::intrinsics::saturating_sub - Rust
Description: API documentation for the Rust `saturating_sub` fn in crate `std`.
Keywords: rust, rustlang, rust-lang, saturating_sub

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

    pub const extern "rust-intrinsic" fn saturating_sub<T>(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

Computes `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, `std::u32::saturating_sub`
