Expand description
A mapper that translates offset:length bytes to 1-based line:row characters.
Implementations
sourceimpl Mapper
impl Mapper
sourcepub fn new_utf16(source: &str, one_based: bool) -> Self
pub fn new_utf16(source: &str, one_based: bool) -> Self
Creates a new Mapper that remembers where each line starts and ends.
Uses UTF-16 character sizes for positions.
sourcepub fn new_utf8(source: &str, one_based: bool) -> Self
pub fn new_utf8(source: &str, one_based: bool) -> Self
Uses UTF-8 character sizes for positions.
pub fn offset(&self, position: Position) -> Option<TextSize>
pub fn text_range(&self, range: Range) -> Option<TextRange>
pub fn position(&self, offset: TextSize) -> Option<Position>
pub fn range(&self, range: TextRange) -> Option<Range>
pub fn mappings(
&self
) -> (&BTreeMap<TextSize, Position>, &BTreeMap<Position, TextSize>)
pub fn line_count(&self) -> usize
pub fn all_range(&self) -> Range
