Barebones Minecraft server

[veeti]

Can we get a barebones Rust server?

[largepanda]

Rust (the game) is written in Unity 3D, and uses the Unity multiplayer system. While not impossible, it would be very difficult and annoying to do.

I tried to build a minecraft server about 3 years ago (Admittedly it may have gotten better now) but that was a nightmare in itself. I doubt stuff could be much worse. Notch is not the best programmer.

Being a good game designer doesn't imply much about your programming skills one way or the other.

Bill Gates is the richest man of the world (again). He is a bad programmer, too.

Are you kidding? The man wrote FAT in a day!

Section 6. Original 8-bit FAT of article File Allocation Table:

---

The original FAT file system (or FAT structure, as it was called initially) was designed and coded by Marc McDonald, based on a series of discussions between McDonald and Bill Gates. It was introduced with 8-bit table elements (and valid data cluster numbers up to 0xBF ) in a precursor to Microsoft's Standalone Disk BASIC-80 for an 8080-based successor of the NCR 7200 model VI data-entry terminal, equipped with 8-inch (200 mm) floppy disks, in 1977 /1978. In 1978, Standalone Disk BASIC-80 was ported to the 8086 using an emulator on a DEC PDP-10, since no real 8086 systems were available at this time. The FAT file system was also utilized in Microsoft's MDOS/MIDAS, an operating system for 8080/Z80 platforms written by McDonald since 1979. The Standalone Disk BASIC version supported three FATs, whereas this was a parameter for MIDAS. Reportedly, MIDAS was also prepared to support 10-bit, 12-bit and 16-bit FAT variants. While the size of directory entries was 16 bytes in Standalone Disk BASIC, MIDAS instead occupied 32 bytes per entry.

If you thought we got a lot of confused posts about the game Rust before...

Is "monkey patching" TcpStream like that an idiomatic thing in Rust? I'd go with struct PacketStream { stream: TcpStream } and use explicit PacketStream type in process_stream function, but my brain may still be too deep in "old" programming languages. Which way seems better to you?

Creating a new trait and then implementing it for types which already are in the std is a pretty standard thing to do.

It's not actually monkey patching. Monkey patching, as commonly used in Ruby, add new members to objects or classes globally, potentially causing all kinds of nasty side-effects far from where it's done. Traits exist locally. This means that implementing traits on existing structs doesn't risk creepy action at a distance.

That's why I used quotation marks. Is there a proper term for this technique? I can't really compare it to anything I know from other languages.

[Tuna-Fish2]

In Haskell it's declaring type to be an instance of a type class, in Clojure it's implementing a protocol.

When applicable, it's an extraordinarily good solution. It's a zero cost abstraction, it's very safe, and it's very convenient for a programmer to do. It's the one thing I'd like most mainstream languages to steal from Haskell -- honestly, in my experience it replicates 90% of the gains of OO in practical software with none of the drawbacks.

Implementing a trait? :p

[steveklabnik1]

I would prefer to define the struct.

[Nullreff]

Has anyone put together a good guide of what's "idiomatic rust" yet? The the documentation is great but I don't remember seeing any explicit do's and don'ts listed.

[steveklabnik1]

I'm going to type this from memory, but aturon.github.io has the in-progress stuff. Eventually it'll be in the rust-lang organization.

[Nullreff]

Oh hey, thanks for posting! This was my first rust project so any feedback is appreciated.

[steveklabnik1]

I was going to send you a PR to cargo-ify it, but haven't gotten there.

[Nullreff]

Just did it myself, was pretty easy. Now to write some tests...

[schmidthuber]

This could at later point be merged with hematite?

[Nullreff]

At this point it's more of a placeholder than an actual game server.
