Function bitintr::x86::bmi2::bzhi

pub fn bzhi<T: Int>(x: T, bit_position: T) -> T

Zero the high bits of x at position >= bit_position.

Panics

If bit_position >= bit_size() the behavior is undefined (panics in debug builds).

Assembly Instructions

• BZHI:
  • Description: Zero high bits starting with specified bit position.
