Struct LineFragment 

pub struct LineFragment {
    pub text: String,
    pub style: InlineStyle,
    pub font: Arc<Font>,
    pub font_size: f64,
    pub x: f64,
    pub width: f64,
    pub ascent: f64,
    pub descent: f64,
    pub start_byte: usize,
}

One piece of a run as it sits on a single visual line: the smallest unit the painter draws. A wrapped run may contribute several fragments (one per line); adjacent same-style pieces on a line are merged into one fragment.

Fields

text: String

The fragment’s characters.

style: InlineStyle

The inline style shared by every character in the fragment.

font: Arc<Font>

Font this fragment was shaped/measured with (from the resolver).

font_size: f64

Font size (points) used for this fragment.

x: f64

X offset of this fragment’s left edge from the start of the line’s text.

width: f64

Advance width of the fragment.

ascent: f64

Ascent (px above baseline) at this fragment’s size.

descent: f64

Descent (px below baseline) at this fragment’s size.

start_byte: usize

Byte offset into the owning block’s flattened text where this fragment’s text begins. Within a line, kept fragments are byte-contiguous (dropped soft-wrap spaces only occur between lines), so this plus text.len() yields the fragment’s exclusive byte end. The interactive editor uses it to map caret DocPos byte offsets to/from pixel geometry.

Trait Implementations

impl Clone for LineFragment

fn clone(&self) -> LineFragment

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
