Struct SourceMap 

pub struct SourceMap {
    pub file_registry: FileRegistry,
    /* private fields */
}

Maps byte offsets in expanded text back to original source locations.

The source map records one SourceOrigin per line of expanded output. To resolve a byte offset from pest, we convert it to a line number (by counting newlines), then look up the origin for that line.

Fields

file_registry: FileRegistry

Implementations

impl SourceMap

pub fn new(file_registry: FileRegistry, line_origins: Vec<SourceOrigin>) -> Self

pub fn resolve( &self, byte_offset: usize, expanded_source: &str, ) -> &SourceOrigin

Resolve a byte offset in the expanded source to its original location

pub fn resolve_span( &self, span: &Range<usize>, expanded_source: &str, ) -> &SourceOrigin

Remap a span (byte range) from expanded source to an original origin. Uses the start of the span for resolution.

pub fn len(&self) -> usize

Get the number of tracked output lines

pub fn is_empty(&self) -> bool

pub fn format_location(&self, origin: &SourceOrigin) -> String

Format a human-readable location string for diagnostics

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.
