Struct SourceMappingResult 

pub struct SourceMappingResult {
    pub segments: Vec<MappingSegmentResult>,
    pub generated_regions: Vec<GeneratedRegionResult>,
}

Complete source mapping information for a macro expansion.

Contains both preserved segments (original code that wasn’t modified) and generated regions (new code synthesized by macros).

Usage

This mapping enables:

• Converting positions from original source to expanded source and vice versa
• Identifying which macro generated a given piece of code
• Mapping IDE diagnostics from expanded code back to original source

Fields

segments: Vec<MappingSegmentResult>

Segments mapping preserved regions between original and expanded source. Sorted by position for efficient binary search lookups.

generated_regions: Vec<GeneratedRegionResult>

Regions in the expanded source that were generated by macros. Used to identify synthetic code with no original source location.
