This example allows to send and receive files through TCP.
First, choose a file to send it. If it's big, better!
If you are in linux, you can create a 1GB file with the following command:
truncate -s 1G <filename>
Launch the receiver in a terminal. It acts as a server, being able to receive files from several clients at the same time.
cargo run --example file-transfer recv
Run a sender with a file path (one sender per terminal):
cargo run --example file-transfer send <file_path>
Note: You can play the with disconnections using ctrl-c over the sender/receiver.
The file is sent in chunks to not block the EventQueue if the transfer is really long.
