Indexed Ring Buffer

An indexed multiple readable spsc ring buffer.

Overview

  • access by an absolute index.
  • a single-producer single-consumer with multi-reader.
  • using RwLock of parking_lot.

Examples

extern crate indexed_ring_buffer;
use indexed_ring_buffer::*;

let (mut p, mut c, r) = indexed_ring_buffer::<usize>(0, 5);

for i in 0..101 {
    p.push(i);
    c.shift();
}

for i in 101..106 {
    p.push(i);
}

let (start, end, data) = r.get_from(101,5).unwrap();
assert_eq!(data,vec![101,102,103,104,105]);
assert_eq!(start,101);
assert_eq!(end,105);

c.shift_to(105);
let rslt = r.get_all();
assert_eq!(rslt,None);
