Crate fixed_buffer_tokio

This is a Rust library with fixed-size buffers, useful for network protocol parsers and file parsers.

This is the tokio async version of fixed-buffer.

Features

• Write bytes to the buffer and read them back
• Lives on the stack
• Does not allocate memory
• Use it to read a stream, search for a delimiter, and save leftover bytes for the next read.
• Easy to learn & use. Easy to maintain code that uses it.
• Depends only on std, tokio 0.3, and fixed-buffer.
• Works with Tokio 0.3 and Rust latest, beta, and nightly
• No macros
• Good test coverage (98%)

Structs

AsyncFixedBuf	A newtime that wraps FixedBuf and implements tokio::io::AsyncRead and tokio::io::AsyncWrite.
AsyncReadWriteChain	A wrapper for a pair of structs. The first implements AsyncRead. The second implements AsyncRead+AsyncWrite.
AsyncReadWriteTake	Wraps a struct that implements AsyncRead+AsyncWrite. Passes through reads and writes to the struct. Limits the number of bytes that can be read.
