Implementations§

Source§

impl SourceMap

Source

pub fn new() -> Self

Konstruiert eine leere SourceMap.

Source

pub fn add_file(&mut self, name: &str) -> FileId

Registriert eine Datei und liefert ihre stabile FileId.

Source

pub fn record_segment( &mut self, output_start: usize, length: usize, file_id: FileId, original_offset: usize, )

Schreibt ein Segment ein. output_start und length beziehen sich auf den expanded-String; original_offset zeigt auf die erste Byte-Position in der file_id-Source.

Source

pub fn lookup(&self, output_pos: usize) -> Option<SourceLocation>

Loest eine expanded-Position auf die Original-(Datei,Offset). Liefert None, wenn die Position nicht in einem registrierten Segment liegt (z.B. zwischen zwei Segmenten oder hinter dem letzten).

Source

pub fn file_name(&self, id: FileId) -> Option<&str>

Datei-Name fuer eine FileId.

Source

pub fn segment_count(&self) -> usize

Anzahl registrierter Segmente.

Source

pub fn file_count(&self) -> usize

Anzahl registrierter Dateien.
