Struct TaggedString

pub struct TaggedString {
    pub styled_text: (U16String, Vec<u8>),
    pub sections: Vec<SectionOptions>,
    pub supports_vertical_writing_mode: Option<bool>,
    pub image_section_id: u16,
}

A TaggedString is the shaping-code counterpart of the Formatted type Whereas Formatted matches the logical structure of a ‘format’ expression, a TaggedString represents the same data at a per-character level so that character-rearranging operations (e.g. BiDi) preserve formatting. Text is represented as:

• A string of characters
• A matching array of indices, pointing to:
• An array of SectionsOptions, representing the evaluated formatting options of the original sections.

Once the guts of a TaggedString have been re-arranged by BiDi, you can iterate over the contents in order, using getCharCodeAt and getSection to get the formatting options for each character in turn. maplibre/maplibre-native#4add9ea original name: TaggedString
