Struct SourceMap 

pub struct SourceMap(pub Vec<(usize, SourceLine)>);

Generated by preprocessor: Sparse map of result (Span) line number to a tuple of file name and line number. This allows us to work backwards from the pre-processed and unified Span to the various inputs that were used to construct it. Line numbers here are 1-based.

Tuple Fields

0: Vec<(usize, SourceLine)>

Implementations

impl SourceMap

pub fn original_file_and_line(&self, key: usize) -> Option<SourceLine>

Given a 1-based line number in the preprocessed source file, translate that to a file name and line number as original inputs to the parsing process.

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.

impl Default for SourceMap

fn default() -> SourceMap

Returns the “default value” for a type.

impl PartialEq for SourceMap

fn eq(&self, other: &SourceMap) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
