Struct p8n_types::Constant

pub struct Constant {
    pub value: u64,
    pub bits: usize,
}

A constant value.

Fields

value: u64

Value

bits: usize

Size of the value in bits. Never zero.

Methods

impl Constant

pub fn new(value: u64, bits: usize) -> Result<Constant>

Create a new constant. Fails if bits is zero.

pub fn mask(&self) -> Wrapping<u64>

Returns a bit mask covering all bits of the constant. Returns u64::MAX if bits > 64.
