Struct ConcatBuilder 

pub struct ConcatBuilder { /* private fields */ }

Builder for concatenating multiple source maps into one.

Each added source map is offset by a line delta, producing a single combined map. Sources and names are deduplicated across inputs.

Implementations

impl ConcatBuilder

pub fn new(file: Option<String>) -> Self

Create a new concatenation builder.

pub fn add_map(&mut self, sm: &SourceMap, line_offset: u32)

Add a source map to the concatenated output.

line_offset is the number of lines to shift all mappings by (i.e. the line at which this chunk starts in the output).

pub fn to_json(&self) -> String

Finish building and return the concatenated source map as JSON.

pub fn build(&self) -> SourceMap

Finish building and parse the result into a SourceMap.
