Function catch_panic

src/util.rs:134–157

Run `f` inside [`panic::catch_unwind`], logging and swallowing any panic. Returns `Some(value)` on success and `None` on panic. The error message includes `label` (the operation name, e.g. `"hover"` or `"goto_definition"`), `uri`, and the optional cursor `position`. This centralises the boilerplate that every LSP handler uses to guard against stack overflows and unexpected panics in the resolut
