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

    pub extern "rust-intrinsic" fn add_with_overflow<T: Copy>(
        x: T,
        y: T
    ) -> (T, bool)

🔬 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

Performs checked integer addition.

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 `overflowing_add` method. For example, `u32::overflowing_add`
