Struct apint::BitWidth

pub struct BitWidth(_);

The BitWidth represents the length of an APInt.

Its invariant restricts it to always be a positive, non-zero value. Code that built's on top of BitWidth may and should use this invariant.

Methods

impl BitWidth

Constructors

fn w1() -> Self

Creates a BitWidth that represents a bit-width of 1 bit.

fn w8() -> Self

Creates a BitWidth that represents a bit-width of 8 bits.

fn w16() -> Self

Creates a BitWidth that represents a bit-width of 16 bits.

fn w32() -> Self

Creates a BitWidth that represents a bit-width of 32 bits.

fn w64() -> Self

Creates a BitWidth that represents a bit-width of 64 bits.

fn from_usize(val: usize) -> Result<Self>

Creates a BitWidth from the given usize.

Errors

• When encountering a given bitwidth of zero (0).

impl BitWidth

API

fn to_usize(self) -> usize
