Struct SourceMap 

pub struct SourceMap { /* private fields */ }

Where each code point of a normalised string came from in its source.

Filled by Normalizer::normalize_mapped. All positions are code-point indices; utf8_range and utf16_range convert a range of the source to bytes or UTF-16 units.

Implementations

impl SourceMap

pub fn new() -> Self

An empty map.

pub fn len(&self) -> usize

Number of code points of the normalised string.

pub fn is_empty(&self) -> bool

Whether the normalised string is empty.

pub fn source_len(&self) -> usize

Number of code points of the source.

pub fn source_of(&self, i: usize) -> Option<usize>

The source code point that produced normalised code point i.

pub fn to_source(&self, range: Range<usize>) -> Option<Range<usize>>

The smallest range of source code points that produced the normalised code points range. It is extended at the end over source characters that produced nothing (a dropped combining mark after the last letter belongs to that letter). An empty range maps to an empty range at the matching source position. None if range is not within 0..=self.len() or is reversed.
