catflap
There is the utility cargo-watch which rebuilds your project when it notices there are changed files. This is very useful when writing web server and you want to have a fast edit, compile, run cycle.
The problem is that when you're using this for a web server the socket that the server uses might still be in use
from the previous run. This makes cargo-watch crash. The solution, from the author of cargo-watch is catflap. It's
another utility that takes ownership of sockets and passes them the program you're running with cargo watch.
To be able to use the sockets provided by catflap you need to read the file descriptor from the environment variable
LISTEN_FD.
This example will how you how to do that on a hello world.
By default the server will be running on port 5000, unless you pass the flag -p 8080 to catflap. Then it will run on
port 8080
Usage
cd actix-web/examples/catflap
catflap -- cargo watch -x run
# Started http server: 127.0.0.1:8080
