Crate linebuffer

linebuffer

A circular-/ringbuffer for dynamic sized elements.

It's created specifically for storing line-like data in a upcounting fashion.

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(), &())));

Details

When creating a linebuffer the amount of elements(lines) and the data size is specified.
This means for 8 elements and a data size of 16 the buffer will wrap when either 8 elements or more than 16 bytes were written. If we would insert 8 elements of 4 bytes, our buffer would thus already wrap after 4 elements.

Please note that the element amount is stack allocated currently. Consequently setting a high amount of elements can lead to stack overflow.
