Struct ExportSymbolExtractor 

pub struct ExportSymbolExtractor;

Export symbol extractor for Exporter-based Perl modules.

This extractor walks the AST to:

1. Detect if a module uses Exporter (via one of four patterns)
2. Parse @EXPORT, @EXPORT_OK, and %EXPORT_TAGS assignments

Implementations

impl ExportSymbolExtractor

pub fn extract(ast: &Node) -> Option<ExportInfo>

Extract export information from an AST.

Returns None only when the module has neither Exporter inheritance (use Exporter;, use parent 'Exporter';, use base 'Exporter';, or @ISA = qw(Exporter ...);) nor a custom sub import { ... } definition. Returns Some(ExportInfo) with empty sets otherwise; modules whose only signal is a custom sub import get custom_import: true and confidence: Low on the returned info.
