async-tftp

This library provides TFTP async implementation. Currently it implements only server side which can serve read requests, which is the most prominent scenario used.

Example

use async_tftp::server::TftpServerBuilder;
use async_tftp::Result;

fn main() -> Result<()> {
   async_std::task::block_on(async {
       let tftpd = TftpServerBuilder::with_dir_ro(".")?.build().await?;
       tftpd.serve().await?;
       Ok(())
   })
}

Features

• Async implementation.
• Serve read requests.
• Unlimited transfer file size (block number roll-over).
• You can set non-standard reply timeout. This is useful for faster file transfer in unstable environments.
• You can set block size limit. This is useful if you are accessing client through a VPN.
• You can implement your own Handler for more advance cases than just serving a directory.

Implemented RFCs

• RFC 1350 - The TFTP Protocol (Revision 2).
• RFC 2347 - TFTP Option Extension.
• RFC 2348 - TFTP Blocksize Option.
• RFC 2349 - TFTP Timeout Interval and Transfer Size Options.
