colcon-cargo
An extension for colcon-core to support Rust projects built with Cargo.
Install
$ pip3 install --user --upgrade git+https://github.com/colcon/colcon-cargo.gitUsage / Minimal example
Build a sample workspace
```sh $ mkdir ws/ $ cd ws/ $ cargo init hello_world $ cargo init hello_world2 $ tree . . ├── hello-world │ ├── Cargo.toml │ └── src │ └── main.rs └── hello-world2 ├── Cargo.toml └── src └── main.rs 4 directories, 4 files ```
Verify that cargo detects the Rust packages:
$ colcon list
hello-world hello-world (cargo)
hello-world2 hello-world2 (cargo)Build them with Cargo:
$ colcon build
Starting >>> hello_world
Starting >>> hello_world_2
Finished <<< hello_world_2 [1.84s]
Finished <<< hello_world [1.94s]
Summary: 2 packages finished [2.34s]Source the generated install/ directory and execute:
$ source install/setup.bash
$ hello-world
Hello, world!
$ hello-world2
Hello, world!Testing
Test the packages with cargo:
$ colcon test
Starting >>> hello_world_2
Starting >>> hello_world
Finished <<< hello_world [0.24s]
Finished <<< hello_world_2 [0.25s]
Summary: 2 packages finished [0.39s]Inspect the test results (cargo test and cargo fmt --check).
They should all succeed for the empty templates:
$ colcon test-result --all
