Builtin type std::builtins::tuple

Method implementations for tuples

Tuples are fixed-size collections of elements of different types. They are often used to return multiple values from a function or to group values of different types together.

A single-element tuple is represented as (T,), where T is the type of the element. An empty tuple () is also known as void.

Methods

• fn len(self: &Tup) -> usize

  source

  Returns the number of elements in the tuple.

  Example

  let tuple = (1, 2, 3);
  assert_eq!(tuple.len(), 3);
  Run this example

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

  source

  Returns true if arguments are equal, false otherwise

  See Equatable for details.

• fn compare(lhs: &Tup, rhs: &Tup) -> Ordering

  source

  Compare the value

  See Comparable for details.

• fn hash<H>(lhs: &Tup, h: &mut H)

  H: Hasher<H>

  source

  Update hasher state with the contents of this object.

  See Hashable for details.

Mixins

• mixin Equatable<Tup>

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

  source

  Returns false if arguments are equal, true otherwise

• mixin Comparable<Tup>

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

  source

  Returns true if lhs is strictly less than rhs, false otherwise

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

  source

  Returns true if lhs is less or equal to rhs, false otherwise

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

  source

  Returns true if lhs strictly greater than rhs, false otherwise

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

  source

  Returns true if lhs greater than or equal rhs, false otherwise
