ensured_bufreader
Overview
ensured_bufreader provides EnsuredBufReader that ensured length bytes in its buffer if it can read from underlying reader.
std::io::BufReader doesn't read bytes from underlying reader if it has buffered bytes.
This behavior is better if you need buffering for performance.
But, if you need buffering for algorithm such as peeking N bytes, BufReader donesn't ensure N bytes in its buffer.
If there are too few bytes in buffer when .fill_buf() called, EnsuredBufReader tries to read additional bytes from underlying reader and keep .fill_buf()?.len() > ensured.
Comparition with other crates
buffered-reader provides same functionality as this crate.
