JS Source Scopes

This crate provides functionality for extracting and processing scope information from JavaScript source files, and resolving that scope via SourceMaps.

Features

• Extracting scopes from source text using extract_scope_names
• Fast lookup of scopes by byte offset using ScopeIndex
• Fast conversion between line/column source positions and byte offsets using SourceContext
• Resolution of minified scope names to their original names using NameResolver
