Expand description
Arbitrary-precision integers.
This module provides support for arbitrary-precision integers of type
Integer
. Instances of Integer
always have a heap allocation for the bit
data; if you want a temporary small integer without heap allocation, you can use
the SmallInteger
type.
Examples
use rug::{integer::SmallInteger, Assign, Integer};
let mut int = Integer::from(10);
assert_eq!(int, 10);
let small = SmallInteger::from(-15);
// `small` behaves like an `Integer` in the following line:
int.assign(small.abs_ref());
assert_eq!(int, 15);
Structs
Used to get a reference to an Integer
.
An error which can be returned when parsing an Integer
.
A small integer that does not require any memory allocation.
An error which can be returned when a checked conversion from Integer
fails.
Enums
Whether a number is prime.
Traits
Types implementing this trait can be converted to SmallInteger
.
