Struct Mapping 

pub struct Mapping {
    pub generated_line: u32,
    pub generated_column: u32,
    pub source: Option<u32>,
    pub original_line: u32,
    pub original_column: u32,
    pub name: Option<u32>,
    pub is_range_mapping: bool,
}

A mapping from a generated position to an original position.

Used with SourceMapGenerator to define position relationships. All positions are 0-based.

Fields

generated_line: u32

0-based line in the generated output.

generated_column: u32

0-based column in the generated output.

source: Option<u32>

Source index from SourceMapGenerator::add_source, or None for generated-only.

original_line: u32

0-based line in the original source.

original_column: u32

0-based column in the original source.

name: Option<u32>

Name index from SourceMapGenerator::add_name, or None.

is_range_mapping: bool

Whether this mapping is a range mapping (ECMA-426 rangeMappings proposal).
