//! `Bytelines` is a simple library crate which offers line iteration for
//! `BufRead` via `&[u8]` rather than `String`.
//!
//! Due to the removal of checking for `String` validity, this is typically
//! much faster for reading in raw data and much more flexible. The APIs
//! offered in this crate are intended to function exactly the same as the
//! `lines` function inside the `BufRead` trait, except that the bytes which
//! precede the line delimiter are not validated.
//!
//! Performance of [ByteLines](enum.ByteLines.html) is practically identical
//! to that of writing a `loop` manually, due to the avoidance of allocations.
