Function catch_panic_unwind_safe

src/util.rs:166–173

Convenience wrapper around [`catch_panic`] for closures that capture `&self` or other non-[`UnwindSafe`] references. Wraps `f` in [`AssertUnwindSafe`] before forwarding to [`catch_panic`]. This is safe in our context because a panic during LSP handling never leaves shared state in an inconsistent state (the worst case is a stale cache entry).

(
    label: &str,
    uri: &str,
    position: Option<Position>,
    f: impl FnOnce() -> T,
)

/// during LSP handling never leaves shared state in an inconsistent
/// state (the worst case is a stale cache entry).
pub(crate) fn catch_panic_unwind_safe<T>(
    label: &str,
    uri: &str,
    position: Option<Position>,
    f: impl FnOnce() -> T,
) -> Option<T> {
    catch_panic(label, uri, position, AssertUnwindSafe(f))
}
