Struct bigmaths::BigInt

pub struct BigInt { /* fields omitted */ }

An arbitrary-precision integer. Addition and substraction are now supported.

Methods

impl BigInt

fn to_isize(&self) -> Option<isize>

Attempts to convert self to isize, returning None if overflow occurred.

fn sign(&self) -> Sign

Returns the sign.

fn limbs(&self) -> Vec<usize>

Returns the digits of the number with radix std::usize::MAX + 1.

Trait Implementations

impl Debug for BigInt

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for BigInt

fn eq(&self, __arg_0: &BigInt) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &BigInt) -> bool

This method tests for !=.

impl Clone for BigInt

fn clone(&self) -> BigInt

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
