Module diagnostics 

Constants

PHP_LSP_SOURCE

Functions

diagnostics_from_doc

Build LSP diagnostics from an already-parsed document. Separated from parse_document_no_diags so the workspace-scan path can skip the allocation entirely.

merge_file_diagnostics

Merge per-file diagnostic categories into one ordered Vec.

parse_document

Parse source and return the (owned) ParsedDoc plus any parse diagnostics.

parse_document_no_diags

Parse source without converting parse errors into LSP Diagnostics.
