ring-vec

A zero-dependency, no-std compatible, producer-consumer, fixed-size, item-oriented ring buffer backed by a vector.

Requires alloc, for the vector.

Status

Brand new, with basic tests, seems to work.

Usage

    #[test]
    fn works() {
        let mut q: RingVec<usize> = RingVec::new(1);
        assert_eq!(q.peek(), None);
        assert_eq!(q.pop(), None);
        assert_eq!(q.push(1), Ok(()));
        assert_eq!(q.peek(), Some(&1));
        assert_eq!(q.pop(), Some(1));
        assert_eq!(q.peek(), None);
        assert_eq!(q.pop(), None);
        assert_eq!(q.push(2), Ok(()));
        assert_eq!(q.peek(), Some(&2));
        assert_eq!(q.push(3), Err(3));
        assert_eq!(q.pop(), Some(2));
        assert_eq!(q.push(4), Ok(()));
        assert_eq!(q.peek(), Some(&4));
        assert_eq!(q.pop(), Some(4));
        assert_eq!(q.peek(), None);
        assert_eq!(q.pop(), None);
        assert_eq!(q.peek(), None);
    }
