Struct ramp::ll::limb_ptr::Limbs

pub struct Limbs { /* fields omitted */ }

A version of *const Limb that is bounds-checked when debug assertions are on

Methods

impl Limbs

unsafe fn new(base: *const Limb, start: i32, end: i32) -> Limbs

Create a new instance, pointing at base and valid from base.offset(start) to base.offset(end).

unsafe fn offset(self, x: isize) -> Limbs

Move self to point to the xth Limbs from the current location.

Methods from Deref<Target = Limb>

const BITS: usize

const B: Limb

fn high_part(self) -> Limb

Returns the high half of the limb

fn low_part(self) -> Limb

Returns the low half of the limb

fn add_overflow(self, other: Limb) -> (Limb, bool)

Performs self + other, returning the result and whether or not the addition overflowed

fn sub_overflow(self, other: Limb) -> (Limb, bool)

Performs self - other, returning the result and whether or not the subtraction overflowed

fn mul_lo(self, other: Limb) -> Limb

Performs self * other returning the lower half of the product

fn mul_hi(self, other: Limb) -> Limb

Performs self * other returning the higher half of the product

fn mul_hilo(self, other: Limb) -> (Limb, Limb)

Performs self * other returning the two-limb result as (high, low).

fn invert(self) -> Limb

fn high_bit_set(self) -> bool

Returns whether or not the highest bit in the limb is set.

Division algorithms often require the highest limb of the divisor to be d >= BASE/2.

fn leading_zeros(self) -> BaseInt

Returns the number of leading zeros in the limb

fn trailing_zeros(self) -> BaseInt

Returns the number of trailing zeros in the limb
