Description

For example, there is lalrpop that is basically a DSL that mixes rust and custom constructs. It should be possible to let rust_analyzer analyze this.

I think it would be good if there's some kind of API to let end user to implement this.

Research direction

The issue names rust-analyzer and lalrpop as the motivating external DSL case, but identifies no files, tests, or existing extension point. Start by tracing how rust-analyzer currently parses Rust and produces diagnostics, then determine the API boundaries needed for end users to integrate external DSL analysis. Done should include a defined, usable external-parser integration path.
