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

    pub extern "rust-intrinsic" fn likely(b: bool) -> 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

Hints to the compiler that branch condition is likely to be true. Returns the value passed to it.

Any use other than with `if` statements will probably not have an effect.
