Expand description

The Popable trait allows popping elements from the front and back of the tuple.

The Unit type is not Popable. All Tuples are Popable.

The take() provides another way to take out elements by their type.

Required Associated Types§

source

type PopFrontOutput: TupleLike

The type of tuple generated by popping an element from the front of the tuple.

source

type PopFrontElemet

The type of the element popped from the front of the tuple.

source

type PopBackOutput: TupleLike

The type of tuple generated by popping an element from the back of the tuple.

source

type PopBackElement

The type of the element popped from the back of the tuple.

Required Methods§

source

fn pop(self) -> (Self::PopBackOutput, Self::PopBackElement)

Pop an element from the back of the tuple.

§Examples

use tuplez::*;

let tup = tuple!(1, "hello", 3.14);
let (tup2, popped) = tup.pop();
assert_eq!(tup2, tuple!(1, "hello"));
assert_eq!(popped, 3.14);

source

fn pop_front(self) -> (Self::PopFrontOutput, Self::PopFrontElemet)

Pop an element from the front of the tuple.

§Examples

use tuplez::*;

let tup = tuple!(1, "hello", 3.14);
let (tup2, popped) = tup.pop_front();
assert_eq!(tup2, tuple!("hello", 3.14));
assert_eq!(popped, 1);
