Const_Queue is an implementation of a queue backed by an array, that is suitable for environments where no standard library exists (only libcore).
Const_Queue implements a ringbuffer to store its items. The implementation will always leave one free slot between the last and the first item of the buffer. This means, that ´ConstQueue<T,4>´ will effectively only hold 3 items.
let mut q = ConstQueue::<i32, 3>::new();
let _ = q.push(10);
let _ = q.push(20);
assert!(q.pop().unwrap() == 10);
assert!(q.pop().unwrap() == 20);
We also support iterators:
let mut q = ConstQueue::<i32, 4>::new();
let _ = q.push(10);
let _ = q.push(20);
let mut values = Vec::<i32>::new();
for i in q.into_iter()
{
values.push(i);
}
assert!(values == vec![10,20]);
