If you don't have the semmle-code repo you may need to install Bazel manually, e.g. from https://github.com/bazelbuild/bazelisk.

This approach uses a released codeql version and is simpler to use for QL development. From your semmle-code directory run:

bazel run @codeql//rust:rust-installer

You now need to create a per-user CodeQL configuration file and specify the option:

--search-path PATH/TO/semmle-code/ql

(wherever the codeql checkout is on your system)

You can now use the Rust extractor e.g. to run Rust tests from the command line or in VSCode.

This approach allows you to build a Rust extractor with a CLI built from source. From your semmle-code directory run:

./build target/intree/codeql-rust

You can now invoke it directly, for example to run some tests:

./target/intree/codeql-rust/codeql test run ql/rust/ql/test/PATH/TO/TEST/
