Description: API documentation for the Rust `likely` fn in crate `core`.

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

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

Unstable (`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.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
