Struct RangeMapper 

pub struct RangeMapper { /* private fields */ }

Remaps ranges.

Useful in combination with SyntaxNode::synthesize_mapped to have accurate error spans for source text that is non-consecutive in its source file (for instance, Typst code in a doc comment with start-of-line slashes).

Implementations

impl RangeMapper

pub fn new( segments: impl IntoIterator<Item = Range<usize>>, ) -> Result<Self, EcoString>

Creates a new range mapper.

The iterator should returns ranges in the original text that will be consecutively concatenated to produce the derived text.

Segments should be in order. (The start of a later range must not precede the end of an earlier range.)

Note that this representation implies that ranges can only ever increase in their start position and length when mapped.

Trait Implementations

impl Hash for RangeMapper

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.
