Bash.ExecutionResult protocol (Bash v0.3.0)

Copy Markdown View Source

Protocol for extracting execution results from various result types.

This protocol provides a unified interface for both:

  • CommandResult structs (which still have output for external commands)
  • AST nodes with embedded execution results (output goes to sinks)

Note: stdout/stderr/all_output functions return results from the collector for Script types, and empty strings for AST nodes since output goes to sinks.
