Trait BitWidth 

pub trait BitWidth: Sized {
    // Required method
    fn bit_width(self) -> u32;
}

Computes the minimal number of bits required to represent an unsigned value.

Required Methods

fn bit_width(self) -> u32

Returns the minimum number of bits required to represent self, i.e. BITS - leading_zeros. Returns 0 for 0. Like std, this is only provided for unsigned types.

use const_num_traits::BitWidth;

assert_eq!(BitWidth::bit_width(0u8), 0);
assert_eq!(BitWidth::bit_width(0b0101_0000u8), 7);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
