Enum rug::integer::Order

pub enum Order {
    Lsf,
    LsfLe,
    LsfBe,
    Msf,
    MsfLe,
    MsfBe,
}

The ordering of digits inside a slice, and bytes inside a digit.

Examples

use rug::integer::Order;
use rug::Integer;

let i = Integer::from(0x0102_0304);
let mut buf: [u16; 4] = [0; 4];

// most significant 16-bit digit first, little endian digits
i.write_digits(&mut buf, Order::MsfLe);
assert_eq!(buf, [0, 0, 0x0102u16.to_le(), 0x0304u16.to_le()]);
// least significant 16-bit digit first, big endian digits
i.write_digits(&mut buf, Order::LsfBe);
assert_eq!(buf, [0x0304u16.to_be(), 0x0102u16.to_be(), 0, 0]);

Variants

LsfBe

Least significant digit first, with big endian digits.

Msf

Most significant digit first, with each digit in the target’s endianness.

MsfLe

Most significant digit first, with little endian digits.

MsfBe

Trait Implementations

impl Eq for Order

impl PartialOrd<Order> for Order

fn partial_cmp(&self, other: &Order) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for Order

impl PartialEq<Order> for Order

fn eq(&self, other: &Order) -> bool

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

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Clone for Order

fn clone(&self) -> Order

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for Order

fn cmp(&self, other: &Order) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl Debug for Order

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

Formats the value using the given formatter.

impl Hash for Order

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,

Feeds a slice of this type into the given [Hasher].
