Function std::intrinsics::unchecked_shr[][src]

pub const unsafe extern "rust-intrinsic" fn unchecked_shr<T>(x: T, y: T) -> T where
    T: Copy
🔬 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

Expand description

执行未经检查的右移,导致 y < 0y >= N 出现不确定的行为,其中 N 是 T 的宽度 (以位为单位)。

可通过 checked_shr 方法在整数基元上使用此内联函数的安全包装。 例如, u32::checked_shr
