Struct MixedNumber 

pub struct MixedNumber(pub RBig);

Newtype wrapper providing FromStr for the mixed-number format.

RBig already implements FromStr for the standard "a/b" syntax; this newtype extends parsing to also accept "1 3/4" while keeping the orphan rule satisfied.

Examples

use oxinum_rational::{MixedNumber, RBig, IBig, UBig};
use std::str::FromStr;
let m: MixedNumber = "1 3/4".parse().unwrap();
assert_eq!(m.0, RBig::from_parts(IBig::from(7), UBig::from(4u32)));
let n = MixedNumber::from_str("-2 1/3").unwrap();
assert_eq!(n.0, RBig::from_parts(IBig::from(-7), UBig::from(3u32)));

Trait Implementations

impl Clone for MixedNumber

fn clone(&self) -> MixedNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MixedNumber

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

Formats the value using the given formatter.

impl Display for MixedNumber

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

Formats the value using the given formatter.

impl Eq for MixedNumber

impl FromStr for MixedNumber

type Err = OxiNumError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for MixedNumber

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
