Struct ariadne::Source

pub struct Source { /* fields omitted */ }

Implementations

impl Source

pub fn len(&self) -> usize

pub fn chars(&self) -> impl Iterator<Item = char> + '_

pub fn line(&self, idx: usize) -> Option<&Line>

pub fn lines(&self) -> impl ExactSizeIterator<Item = &Line> + '_

pub fn get_offset_line(&self, offset: usize) -> Option<(&Line, usize, usize)>

Get the line that the given offset appears on, and the line/column numbers of the offset.

Note that the line/column numbers are zero-indexed.

pub fn get_line_range<S: Span>(&self, span: &S) -> Range<usize>

Get the range of lines that this span runs across.

The resulting range is guaranteed to contain valid line indices (i.e: those that can be used for Source::line).

Trait Implementations

fn display(&self, _: &()) -> Option<Box<dyn Display>>

Display the given ID.

impl<S: AsRef<str>> From<S> for Source

fn from(s: S) -> Self
