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

    pub unsafe extern "rust-intrinsic" fn unchecked_add<T: Copy>(
        x: T,
        y: 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

This is supported on non-crate feature `miri-test-libstd` or `test` or `doctest` only.
Expand description

Returns the result of an unchecked addition, resulting in undefined behavior when `x + y > T::MAX` or `x + y < T::MIN`.

This intrinsic does not have a stable counterpart.
