pw_kernel: Kernel experiments

rust_analyzer#

Generating rust-project.json#

For a given $CONFIG in:

  • k_host

  • k_qemu_lm3s6965evb

  • k_rp2350

bazelisk run @rules_rust//tools/rust_analyzer:gen_rust_project -- --config $CONFIG //pw_kernel/...

Errors and warnings in VSCode#

Add this to Pigweed’s .vscode/settings.json. Note that it only builds the kernel targets to limit the amount of time that it takes to run. Substitute $CONFIG for the config chosen above.

"rust-analyzer.check.overrideCommand": [
  "bazelisk",
  "build",
  "--config=$CONFIG",
  "--@rules_rust//:error_format=json",
  "//pw_kernel/..."
],
