Implementations

impl SourceMap

pub fn from_json(json: &str) -> Result<Self, ParseError>

Parse a source map from a JSON string. Supports both regular and indexed (sectioned) source maps.

pub fn original_position_for( &self, line: u32, column: u32, ) -> Option<OriginalLocation>

Look up the original source position for a generated position.

Both line and column are 0-based. Returns None if no mapping exists or the mapping has no source.

pub fn generated_position_for( &self, source: &str, line: u32, column: u32, ) -> Option<GeneratedLocation>

Look up the generated position for an original source position.

source is the source filename. line and column are 0-based.

pub fn source(&self, index: u32) -> &str

Resolve a source index to its filename.

pub fn name(&self, index: u32) -> &str

Resolve a name index to its string.

pub fn source_index(&self, name: &str) -> Option<u32>

Find the source index for a filename.

pub fn mapping_count(&self) -> usize

Total number of decoded mappings.

pub fn line_count(&self) -> usize

Number of generated lines.

pub fn mappings_for_line(&self, line: u32) -> &[Mapping]

Get all mappings for a generated line (0-based).

pub fn all_mappings(&self) -> &[Mapping]

Iterate all mappings.

pub fn to_json(&self) -> String

Serialize the source map back to JSON.

Produces a valid source map v3 JSON string that can be written to a file or embedded in a data URL.

Trait Implementations

impl Clone for SourceMap

fn clone(&self) -> SourceMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SourceMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
