Protocol std::cmp::Equatable

Types that can be compared for equality.

Types that implement this protocol can be compared for equality using the == and != operators. Many built-in types implement this protocol, such as primitive types, slices, Option, etc.

Method equals must be implemented, other methods can be mixed in.

Example

struct Point { x: i32, y: i32 }

impl Point {
    use std::cmp::Equatable;

    fn equals(self: &Point, other: &Point) -> bool {
        self.x == other.x && self.y == other.y
    }
    mixin Equatable<Point>;
}

assert_eq!(Point { x: 1, y: 2 }, Point { x: 1, y: 2 });
assert_ne!(Point { x: 1, y: 2 }, Point { x: 1, y: 3 });

Required methods

• fn equals(lhs: &Self, rhs: &Self) -> bool

  source

  Returns true if arguments are equal, false otherwise

  See Equatable for details.

Provided methods

• fn not_equals(lhs: &Self, rhs: &Self) -> bool

  source

  Returns false if arguments are equal, true otherwise
