normalize-facts-rules-api 0.3.2

//! Relations (facts) that rules operate on.
//!
//! These are the inputs to Datalog rules, extracted from code by normalize-facts.
//! Each relation type maps to a Datalog predicate:
//!
//! - `symbol(file, name, kind, line)` - defined symbols
//! - `import(from_file, to_module, name)` - import statements
//! - `call(caller_file, caller_name, callee_name, line)` - function calls
//! - `visibility(file, name, vis)` - symbol visibility
//! - `attribute(file, name, attr)` - symbol attributes (one per attribute)
//! - `parent(file, child_name, parent_name)` - symbol nesting hierarchy
//! - `qualifier(caller_file, caller_name, callee_name, qual)` - call qualifier
//! - `symbol_range(file, name, start_line, end_line)` - symbol span
//! - `implements(file, name, interface)` - interface/trait implementation
//! - `is_impl(file, name)` - symbol is a trait/interface implementation
//! - `type_method(file, type_name, method_name)` - method signatures on types
//!
//! Cross-file resolution predicates (Phase 0):
//!
//! - `resolved_import(from_file, to_file, imported_name, local_alias, kind)` - resolved imports
//! - `module(file, canonical_module_path)` - canonical module identity of a file
//! - `export(file, name, kind)` - exported symbols
//! - `reexport(from_file, original_file, original_name, exported_as)` - re-export chains
//! - `symbol_use(file, name, line)` - symbol reference/use sites
//! - `resolved_reference(use_file, use_line, def_file, def_name, def_kind)` - resolved symbol refs
//! - `resolved_call(caller_file, caller_name, callee_file, callee_name, line)` - resolved calls
//! - `module_search_path(workspace_root, language, kind, path)` - module search paths
