Struct LineLayout 

pub struct LineLayout {
    pub fragments: Vec<LineFragment>,
    pub width: f64,
    pub height: f64,
    pub ascent: f64,
    pub descent: f64,
    pub align_dx: f64,
    pub baseline_from_top: f64,
    pub start_byte: usize,
    pub end_byte: usize,
}

One visual line within a block.

Fields

fragments: Vec<LineFragment>

The fragments painted on this line, left to right.

width: f64

Total advance width of the line’s text.

height: f64

Line-box height = max(ascent + descent) * LINE_SPACING.

ascent: f64

Tallest ascent across the line’s fragments.

descent: f64

Deepest descent across the line’s fragments.

align_dx: f64

Alignment offset added to every fragment’s x within the text column.

baseline_from_top: f64

Baseline distance measured downward from the top of the line box.

start_byte: usize

Byte offset (into the block’s flattened text) of the first character on this line, and one past the last. A soft-wrapped line’s end_byte excludes the trailing space that was dropped at the wrap point, so a caret byte in that gap falls between end_byte of one line and start_byte of the next. Both are 0 for an empty block’s reserved line.

end_byte: usize

Trait Implementations

impl Clone for LineLayout

fn clone(&self) -> LineLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.
