The Rust package manager, cargo
, allows us to create a new project very easily with just one command, cargo new
. Let's run it as follow:
cargo new tetris --bin
You should have a new folder tetris
containing the following:
tetris/ | |- Cargo.toml |- src/ | |- main.rs
Note that if you ran cargo new
without the --bin
flag, then you will have a lib.rs
file instead of main.rs
.
Now write this into your Cargo.toml
file:
[package] name = "tetris" version = "0.0.1" [dependencies] sdl2 = "0.30.0"
Here, we declare that our project's name is tetris
, its version is 0.0.1
(it isn't really important at the moment), and that it has a dependency on the sdl2
crate.
For the versioning, Cargo
follows SemVer (Semantic Versioning). It works as follows:
[major].[minor].[path]
So here's exactly what every part means:
- Update the
[major]
number version when you make incompatible API changes - Update the
[minor]
number version when adding...
