Struct BitRange

pub struct BitRange {
    pub msb_index: u32,
    pub lsb_index: u32,
}

Structure representing a range of bits in a number.

Example

#[macro_use]
use dbs_arch::cpuid::bit_helper::*;

let range = BitRange {
    msb_index: 7,
    lsb_index: 3,
};

The BitRange specified above will represent the following part of the number 72: +———————————––+—+—+—+—+—+—+—+—+—+—+ | Base 2 Representation of the number | 0 | 0 | 0 | 1 | 0 | 0 | 1 | 0 | 0 | 0 | +———————————––+—+—+—+—+—+—+—+—+—+—+ | bits indexes | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | +———————————––+—+—+—+—+—+—+—+—+—+—+ | BitRange | | | * | * | * | * | * | | | | +———————————––+—+—+—+—+—+—+—+—+—+—+

Fields

msb_index: u32

most significant bit index

lsb_index: u32

least significant bit index

Trait Implementations

impl BitRangeExt<u32> for BitRange

fn get_mask(&self) -> u32

Returns a value of type T that has all the bits in the specified bit range set to 1.

fn is_valid(&self) -> bool

Checks if the current BitRange is valid for type T.

fn check(&self)

Asserts if self.is_valid() returns true.
