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

```rust extern crate indexedringbuffer; use indexedringbuffer::*;

let (mut p, mut c, r) = indexedringbuffer::(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.getfrom(101,5).unwrap(); asserteq!(data,vec![101,102,103,104,105]); asserteq!(start,101); asserteq!(end,105);

c.shiftto(105); let rslt = r.getall(); assert_eq!(rslt,None);
