Struct SourceMapDecoder 

pub struct SourceMapDecoder { /* private fields */ }

Decoder for efficient source map lookups.

This provides O(log n) lookup for original positions from generated positions.

Implementations

impl SourceMapDecoder

pub fn new(source_map: SourceMap) -> Result<Self>

Creates a new decoder from a source map.

pub fn lookup( &self, generated_line: u32, generated_column: u32, ) -> Option<&Mapping>

Looks up the original position for a generated position.

pub fn lookup_full( &self, generated_line: u32, generated_column: u32, ) -> Option<OriginalPosition>

Looks up the original position and returns full information.

pub fn get_line_mappings(&self, line: u32) -> Option<&[BoundedMapping]>

Returns all mappings for a generated line.

pub fn generated_line_count(&self) -> usize

Returns the number of lines in the generated file.

pub fn source_map(&self) -> &SourceMap

Returns the underlying source map.

pub fn iter_mappings(&self) -> impl Iterator<Item = &BoundedMapping>

Iterates over all mappings.
