i wrote a bittorrent client in rust for fun
download speed is not too good from my testing i've seen the running average hit 1 MB/s at best.
didn't do uploading just yet so this client is just a leecher (sorry 😢)
some data corruption as well, hopefully i can sort that out. it's not too terrible though.
still some concurrency / contention issues that make it slow for larger number of peers. it works though i think
