WORKING

This repo is only a snapshot to show my Rust learning speed, the applicability of my non-Rust background to Rust programming, and knowledge of Rust features. This is not a port so some time went into logic, too.

https://github.com/kermit4/first_8_hours_of_rust (this repo) https://github.com/kermit4/first_16_hours_of_rust
https://github.com/kermit4/multisource_udp_uploader.rs.git (latest version but not time tracking any more)

If run with no args, it will listen for uploads.

With args it will send a file. (It does not exit when it's done, and it may stall as there is no timer yet.)

i.e.

cargo build
./target/debug/udp_uploader &
sleep 1
./target/debug/udp_uploader /etc/passwd 127.0.0.1:34254

should result in a file called "f000.." with the same content

DONE:

* retransmission
* transmission window scaling

TODO:

* recovery from complete stall
* use real hash
* use larger than 32 byte blocks (damn serde limit!)
* tail end of transfer has a lot of dups
* better variable names
* reduce code duplication and break up long receive() function
