# Trait core::cmp::PartialEq 1.0.0 [−] [src]

    pub trait PartialEq<Rhs: ?Sized = Self> {
        fn eq(&self, other: &Rhs) -> bool;

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

Trait for equality comparisons which are partial equivalence relations.

This trait allows for partial equality, for types that do not have a full equivalence relation. For example, in floating point numbers `NaN != NaN`, so floating point types implement `PartialEq` but not `Eq`.

Formally, the equality must be (for all `a`, `b` and `c`):

- symmetric: `a == b` implies `b == a`; and
- transitive: `a == b` and `b == c` implies `a == c`.

Note that these requirements mean that the trait itself must be implemented symmetrically and transitively: if `T: PartialEq<U>` and `U: PartialEq<V>` then `U: PartialEq<T>` and `T: PartialEq<V>`.

## Derivable

This trait can be used with `#[derive]`. When `derive`d on structs, two instances are equal if all fields are equal, and not equal if any fields are not equal. When `derive`d on enums, each variant is equal to itself and not equal to the other variants.

## How can I implement `PartialEq`?

PartialEq only requires the `eq` method to be implemented; `ne` is defined in terms of it by default. Any manual implementation of `ne` must respect the rule that `eq` is a strict inverse of `ne`; that is, `!(a == b)` if and only if `a != b`.

An example implementation for a domain in which two books are considered the same book if their ISBN matches, even if the formats differ:

    enum BookFormat { Paperback, Hardback, Ebook }
    struct Book {
        isbn: i32,
        format: BookFormat,
    }

    impl PartialEq for Book {
        fn eq(&self, other: &Book) -> bool {
            self.isbn == other.isbn
        }
    }

    let b1 = Book { isbn: 3, format: BookFormat::Paperback };
    let b2 = Book { isbn: 3, format: BookFormat::Ebook };
    let b3 = Book { isbn: 10, format: BookFormat::Paperback };

    assert!(b1 == b2);
    assert!(b1 != b3);Run

# Examples

    let x: u32 = 0;
    let y: u32 = 1;

    assert_eq!(x == y, false);
    assert_eq!(x.eq(&y), false);Run

## Required Methods

### `fn eq(&self, other: &Rhs) -> bool`

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

## Provided Methods

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

This method tests for `!=`.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
