Support tools other than Cargo for `rust-analyzer.check.overrideCommand`

I would like to use Rust Analyzer to show hints in my editor of choice.

I know that I can override the command used to feed data to Rust Analyzer.

{
  "rust-analyzer.check.overrideCommand": [
    "cargo",
    "check",
    "--message-format=json"
  ]
}

The problem is that I am working in a Bazel repository where there is no Cargo. The command that comes close is

bazel build --output_groups=+clippy_checks //...

but it produces no JSON output.

I have created a minimal example in https://github.com/otiv-willem-vanhulle/bazel-rust-check

The bazel rules_rust project https://github.com/bazelbuild/rules_rust does not offer a solution either.

Start by tracing how the rust-analyzer.check.overrideCommand setting is handled and how command output is converted into diagnostics. Use the linked minimal Bazel example to determine the required non-Cargo output and integration behavior. Done means a supported tool other than Cargo can provide the diagnostics needed for editor hints.
