# Rust on CodeQL
|
|
|
|
## Development
|
|
|
|
### Dependencies
|
|
|
|
At present you need to be in the `rust-experiment` branch (or a branch on top of that) in both the `semmle-code` and `codeql` repos.
|
|
|
|
TODO: are there any dependencies that aren't already CodeQL dependencies? bazel and rustc?
|
|
|
|
### Building the Rust Extractor
|
|
|
|
This approach uses a released `codeql` version and is simpler to use for QL development. From your `semmle-code` directory run:
|
|
```bash
|
|
bazel run @codeql//rust:rust-installer
|
|
```
|
|
You now need to create a [per-user CodeQL configuration file](https://docs.github.com/en/code-security/codeql-cli/using-the-advanced-functionality-of-the-codeql-cli/specifying-command-options-in-a-codeql-configuration-file#using-a-codeql-configuration-file) and specify the option:
|
|
```
|
|
--search-path Users/YOURUSERNAME/semmle-code/ql
|
|
```
|
|
(or wherever the `ql` directory is on your system)
|
|
|
|
You can now use the Rust extractor e.g. to run Rust tests from the command line or in VSCode.
|
|
|
|
### Building the Rust Extractor (as a sembuild target)
|
|
|
|
This approach allows you to build a Rust extractor with a CLI built from source. From your `semmle-code` directory run:
|
|
```bash
|
|
./build target/intree/codeql-rust
|
|
```
|
|
You can now invoke it directly, for example to run some tests:
|
|
```bash
|
|
./target/intree/codeql-rust/codeql test run ql/rust/ql/test/PATH/TO/TEST/
|
|
```
