This is a Rust service that uses a custom protocol to send and receive messages over a TCP connection.

Here's the protocol:

Bytes	Name	Description
0-1	Magic Number	Sending a magic number is a common way to ensure that the data you're receiving is what you expect.
2-3	Version Number	start with version 1. We're going to use two bytes, so we have lots of room for future versions.
4-7	Timestamp	a 32-bit unsigned integer to represent the number of seconds since the Unix epoch. This will give us a range of 1970-01-01 to 2106-02-07.
8-11	Payload size	a 32-bit unsigned integer to represent the size of the payload.
12+	Payload	JSON payload.
End-4 - End	CRC32	a CRC32 checksum to ensure that the data we received is the data we expected. Using the crc32fast crate to provide this functionality.

Just open two terminals in collector and server and do cargo run in each to see the action!

If you want to see the dashboard just hit localhost:3000 in your browser.

There's also some REST endpoints you can hit:

api/all - shows all collector data from the database

api/collectors - shows all collectors in the pool

api/collector/{uuid} - shows specific collector data based on provided uuid

api/collector/{uuid}/shutdown - SHUT IT DOWN!
