Module hover 

Functions

class_hover_from_index

Build a hover for a class/interface/trait/enum found by short name in the workspace index.

docs_for_symbol_from_index

Return hover documentation for a symbol from a FileIndex slice.

extract_receiver_var_before_cursor

Extract the receiver variable from immediately before ->word or ?->word at the cursor’s exact column position. Uses the column rather than str::find() so multiple method calls on the same line are handled correctly.

format_params_str

hover_info_with_maps

Indexed variant: uses pre-computed SymbolMaps for the cross-file declaration lookup (path 4/5), eliminating repeated AST walks on stable files. All other paths (named-arg hover, mir-member hover, static-prop hover) still use other_docs since they require full AST traversal.

resolve_use_alias

Resolve a use-import alias to the short class name.

signature_for_symbol_from_index

Return a function/method signature string from a FileIndex slice.
