pub fn unlikely(b: bool) -> bool
Expand description
Hints to the compiler that the branch condition is unlikely to be true. Returns the value passed to it.
This intrinsic is primarily used with if
statements.
Using it in other contexts may not have any effect.
Unlike most intrinsics, this function is safe to call and doesn’t require an unsafe
block.
Therefore, implementations must not require the user to uphold any safety invariants.
