Struct num_bigint::BigUint [−][src]
pub struct BigUint { /* fields omitted */ }Expand description
A big unsigned integer type.
A BigUint-typed value BigUint { data: vec!(a, b, c) } represents a number
(a + b * big_digit::BASE + c * big_digit::BASE^2).
Implementations
Creates and initializes a BigUint.
The digits are in little-endian base 232.
Creates and initializes a BigUint.
The digits are in little-endian base 232.
Assign a value to a BigUint.
The digits are in little-endian base 232.
Creates and initializes a BigUint.
The bytes are in big-endian byte order.
Examples
use num_bigint::BigUint;
assert_eq!(BigUint::from_bytes_be(b"A"),
BigUint::parse_bytes(b"65", 10).unwrap());
assert_eq!(BigUint::from_bytes_be(b"AA"),
BigUint::parse_bytes(b"16705", 10).unwrap());
assert_eq!(BigUint::from_bytes_be(b"AB"),
BigUint::parse_bytes(b"16706", 10).unwrap());
assert_eq!(BigUint::from_bytes_be(b"Hello world!"),
BigUint::parse_bytes(b"22405534230753963835153736737", 10).unwrap());Creates and initializes a BigUint.
The bytes are in little-endian byte order.
Creates and initializes a BigUint. The input slice must contain
ascii/utf8 characters in [0-9a-zA-Z].
radix must be in the range 2...36.
The function from_str_radix from the Num trait provides the same logic
for &str buffers.
Examples
use num_bigint::{BigUint, ToBigUint};
assert_eq!(BigUint::parse_bytes(b"1234", 10), ToBigUint::to_biguint(&1234));
assert_eq!(BigUint::parse_bytes(b"ABCD", 16), ToBigUint::to_biguint(&0xABCD));
assert_eq!(BigUint::parse_bytes(b"G", 16), None);Creates and initializes a BigUint. Each u8 of the input slice is
interpreted as one digit of the number
and must therefore be less than radix.
The bytes are in big-endian byte order.
radix must be in the range 2...256.
Examples
use num_bigint::{BigUint};
let inbase190 = &[15, 33, 125, 12, 14];
let a = BigUint::from_radix_be(inbase190, 190).unwrap();
assert_eq!(a.to_radix_be(190), inbase190);Creates and initializes a BigUint. Each u8 of the input slice is
interpreted as one digit of the number
and must therefore be less than radix.
The bytes are in little-endian byte order.
radix must be in the range 2...256.
Examples
use num_bigint::{BigUint};
let inbase190 = &[14, 12, 125, 33, 15];
let a = BigUint::from_radix_be(inbase190, 190).unwrap();
assert_eq!(a.to_radix_be(190), inbase190);Returns the byte representation of the BigUint in big-endian byte order.
Examples
use num_bigint::BigUint;
let i = BigUint::parse_bytes(b"1125", 10).unwrap();
assert_eq!(i.to_bytes_be(), vec![4, 101]);Returns the byte representation of the BigUint in little-endian byte order.
Examples
use num_bigint::BigUint;
let i = BigUint::parse_bytes(b"1125", 10).unwrap();
assert_eq!(i.to_bytes_le(), vec![101, 4]);Returns the integer formatted as a string in the given radix.
radix must be in the range 2...36.
Examples
use num_bigint::BigUint;
let i = BigUint::parse_bytes(b"ff", 16).unwrap();
assert_eq!(i.to_str_radix(16), "ff");Returns the integer in the requested base in big-endian digit order.
The output is not given in a human readable alphabet but as a zero
based u8 number.
radix must be in the range 2...256.
Examples
use num_bigint::BigUint;
assert_eq!(BigUint::from(0xFFFFu64).to_radix_be(159),
vec![2, 94, 27]);
// 0xFFFF = 65535 = 2*(159^2) + 94*159 + 27Returns the integer in the requested base in little-endian digit order.
The output is not given in a human readable alphabet but as a zero
based u8 number.
radix must be in the range 2...256.
Examples
use num_bigint::BigUint;
assert_eq!(BigUint::from(0xFFFFu64).to_radix_le(159),
vec![27, 94, 2]);
// 0xFFFF = 65535 = 27 + 94*159 + 2*(159^2)Trait Implementations
