Function core::intrinsics::wrapping_sub
source[−]pub extern "rust-intrinsic" fn wrapping_sub<T: Copy>(a: T, b: T) -> T
🔬 This is a nightly-only experimental API. (
core_intrinsics
)Expand description
Returns (a - b) mod 2N, where N is the width of T in bits.
Note that, unlike most intrinsics, this is safe to call;
it does not require an unsafe
block.
Therefore, implementations must not require the user to uphold
any safety invariants.
The stabilized versions of this intrinsic are available on the integer
primitives via the wrapping_sub
method. For example,
u32::wrapping_sub
