Enum FragmentContent 

Source
pub enum FragmentContent {
    Text {
        text: String,
        format: TextFormat,
        offset: usize,
        length: usize,
        element_id: u64,
        word_starts: Vec<u8>,
    },
    Image {
        name: String,
        width: u32,
        height: u32,
        quality: u32,
        format: TextFormat,
        offset: usize,
        element_id: u64,
    },
}
Expand description

A contiguous run of content with uniform formatting within a block.

Offsets are block-relative: offset is the character position within the block where this fragment starts (0 = block start).

Variants§

§

Text

A text run. The layout engine shapes these into glyphs.

Fields

§text: String
§format: TextFormat
§offset: usize

Character offset within the block (block-relative).

§length: usize

Character count.

§element_id: u64

Stable synthesized id for the underlying format run (see synth_element_id). Survives edits that don’t delete the run (character insertions inside the run keep the same id). Used by accessibility layers to build stable NodeIds for AccessKit TextRun children.

§word_starts: Vec<u8>

Unicode word starts within text, expressed as character indices (not byte offsets). Computed per UAX #29 via unicode-segmentation. Fed directly into AccessKit’s set_word_starts on the corresponding Role::TextRun.

§

Image

An inline image. The layout engine reserves space for it.

To retrieve the image pixel data, use the existing TextDocument::resource(name) method.

Fields

§name: String
§width: u32
§height: u32
§quality: u32
§format: TextFormat
§offset: usize

Character offset within the block (block-relative).

§element_id: u64

Stable synthesized id for the underlying image anchor (see synth_element_id).
