linebuffer 0.1.2

LineBuffer - ringbuffer but for elements of different sizes

This crate is specifically for the following use case:

• high throughput of data
• infrequent read of entries or the whole buffer
• entries are distinguishable arrays of bytes
• data has dynamic size
• numbering is infinite

You can use it for example to buffer the stdout of a process per line.
It allows setting the amount of last lines to store and the size of bytes before wrapping.

Example

use linebuffer::{typenum, LineBuffer};

// create a buffer of max 2048 entries/lines and 512KB data cache
// with the additional flag type ()
let mut buffer: LineBuffer<(), typenum::U2048> = LineBuffer::new(512_000);

let data = String::from("Some data stuff");
buffer.insert(data.as_bytes(),());
assert_eq!(buffer.get(0),Some((data.as_bytes(), &())));
