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 < 0
或 y >= 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
