Enum IsbnRef

pub enum IsbnRef<'a> {
    _10(&'a Isbn10),
    _13(&'a Isbn13),
}

An International Standard Book Number, either ISBN10 or ISBN13.

Examples

use isbn::{Isbn, Isbn10, Isbn13};

let isbn_10 = Isbn::_10(Isbn10::new([8, 9, 6, 6, 2, 6, 1, 2, 6, 4]).unwrap());
let isbn_13 = Isbn::_13(Isbn13::new([9, 7, 8, 1, 4, 9, 2, 0, 6, 7, 6, 6, 5]).unwrap());

assert_eq!("89-6626-126-4".parse(), Ok(isbn_10));
assert_eq!("978-1-4920-6766-5".parse(), Ok(isbn_13));

Trait Implementations

impl<'a> Clone for IsbnRef<'a>

fn clone(&self) -> IsbnRef<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for IsbnRef<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a Isbn> for IsbnRef<'a>

fn from(isbn: &'a Isbn) -> Self

Converts to this type from the input type.

impl<'a> From<&'a Isbn10> for IsbnRef<'a>

fn from(isbn: &'a Isbn10) -> Self

Converts to this type from the input type.

impl<'a> From<&'a Isbn13> for IsbnRef<'a>

fn from(isbn: &'a Isbn13) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for IsbnRef<'a>

fn eq(&self, other: &IsbnRef<'a>) -> 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.
