Function permutator::heap_permutation_cell

pub fn heap_permutation_cell<T>(d: &Rc<RefCell<&mut [T]>>, cb: impl FnMut())

Heap permutation which permutate variable d in place and call cb function for each permutation done on d.

Parameter

• d an Rc<RefCell<>> to mutable slice data to be permuted.
• cb a callback function that will be called several times for each permuted value.

Example

use permutator::heap_permutation_cell;
use std::rc::Rc;
use std::cell::RefCell;
let data : &mut[i32] = &mut [1, 2, 3];
let sharable = Rc::new(RefCell::new(data));
heap_permutation_cell(&sharable, || {
    // call other functions/objects that use `sharable` variable.
});

Warning

The permutation is done in place which mean the parameter d will be mutated.

Notes

1. The value passed to callback function will equals to value inside parameter d.
