Crate fixed_buffer_tokio 

NOT MAINTAINED

This crate was replaced by fixed-buffer crates’s tokio feature and read-write-ext-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
• Use it to read a stream, search for a delimiter, and save leftover bytes for the next read.
• Does not allocate memory
• Depends only on std, tokio, and fixed-buffer.
• No macros
• Good test coverage (98%)
• forbid(unsafe_code)

Structs

AsyncFixedBuf

A newtype 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.
