Function set_bits::set

pub fn set(address: usize, start_bit: usize, num_of_bits: usize)

Set num_of_bits bits from the start_bitth bit of address address.

num_of_bits may be more than the number of bits a byte has.

Examples

Set 3 bits from the 2nd bit of specified address.

let byte: Box<u32> = Box::new(0);
let ptr = Box::into_raw(byte);

set_bits::set(ptr as usize, 2, 3);
unsafe {
    assert_eq!(*ptr, 0b11100);
}

// For automatic cleanup.
// See the example of into_raw function.
// https://doc.rust-lang.org/std/boxed/struct.Box.html
let byte = unsafe { Box::from_raw(ptr) };
