Struct SourceMap 

pub struct SourceMap { /* private fields */ }

Maps byte offsets in a source to positions.

The line index is only built when a position is resolved for the first time.

Implementations

impl SourceMap

pub fn new<S: Into<Arc<str>>>(source: S) -> SourceMap

Creates a source map for the given source.

pub fn source(&self) -> &str

Returns the source.

pub fn position(&self, offset: usize) -> Position

Resolves a byte offset into a position.

Offsets beyond the end of the source are clamped.

pub fn span(&self, start: usize, end: usize) -> Span

Resolves a range of byte offsets into a span.
