Struct TextExtractor 

pub struct TextExtractor { /* private fields */ }

Extracts text characters from a DisplayTree by visiting text nodes.

Implementations

impl TextExtractor

pub fn new() -> TextExtractor

Create a new empty text extractor.

pub fn with_rtl(rtl: bool) -> TextExtractor

Create a new text extractor with an RTL base direction hint.

When rtl is true and the icu feature is enabled, bidi reordering uses RTL as the default paragraph direction.

pub fn is_rtl(&self) -> bool

Returns the RTL hint configured for this extractor.

pub fn into_characters(self) -> (Vec<TextCharacter>, Vec<Option<u32>>)

Consume the extractor and return all collected characters with their run IDs.

Trait Implementations

fn default() -> TextExtractor
