Struct MappingSegmentResult 

pub struct MappingSegmentResult {
    pub original_start: u32,
    pub original_end: u32,
    pub expanded_start: u32,
    pub expanded_end: u32,
}

A segment mapping a range in the original source to a range in the expanded source.

These segments form the core of the bidirectional source mapping system, enabling IDE features like “go to definition” and error reporting to work correctly with macro-expanded code.

Invariants

• original_start < original_end
• expanded_start < expanded_end
• Segments are non-overlapping and sorted by position

Fields

original_start: u32

Byte offset where this segment starts in the original source.

original_end: u32

Byte offset where this segment ends in the original source.

expanded_start: u32

Byte offset where this segment starts in the expanded source.

expanded_end: u32

Byte offset where this segment ends in the expanded source.
