Function core::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.

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.

This intrinsic does not have a stable counterpart.
