Module parser 

Rust source file parser built on syn.

Parses .rs files into a structured representation that captures the information the Detector needs: function boundaries, call sites, use imports, and extern blocks. Handles free functions, impl block methods, and trait default methods.

The parser uses syn::visit::Visit to walk the AST. It does not perform type resolution — all matching is done on syntactic path segments. Import aliases are tracked so the Detector can expand them.

Structs

CallSite

A single call expression inside a function body.

ExternBlock

An extern block declaring foreign functions.

ImportPath

A use import statement, with optional alias.

ParsedFile

The parsed representation of a single .rs source file.

ParsedFunction

A single function (free, impl method, or trait default method) and its call sites.

Enums

CallKind

Distinguishes qualified function calls from method calls.

Functions

parse_file

Parses a .rs file from disk into a ParsedFile.

parse_source

Parses Rust source code from a string into a ParsedFile.
