Provides fast indexed access into the input text

Required Methods

fn cat_of_range(&self, range: Range<usize>) -> CategoryType

Common character category inside the range. Indexed by chars.

fn cat_at_char(&self, offset: usize) -> CategoryType

Character category at char offset

fn cat_continuous_len(&self, offset: usize) -> usize

Number of chars to the right of the offset with the same character category

Java name: getCharCategoryContinuousLength

fn char_distance(&self, index: usize, offset: usize) -> usize

Distance in chars between the char indexed by index and the char, relative to it by offset. Java name: getCodePointsOffsetLength

fn orig_slice(&self, range: Range<usize>) -> &str

Returns substring of original text by indices from the current text

fn curr_slice(&self, range: Range<usize>) -> &str

Returns substring of the current (modified) text by indices from the current text

fn to_orig(&self, range: Range<usize>) -> Range<usize>

Translate range from current state to original. Byte-indexed.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
