1//! Config used by the language server.
2//!
3//! We currently get this config from `initialize` LSP request, which is not the
4//! best way to do it, but was the simplest thing we could implement.
5//!
6//! Of particular interest is the `feature_flags` hash map: while other fields
7//! configure the server itself, feature flags are passed into analysis, and
8//! tweak things like automatic insertion of `()` in completions.
