Function permutator::heap_permutation_cell
source · Expand description
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
- The value passed to callback function will equals to value inside parameter
d
.
