Struct Layout 

pub struct Layout {
    pub glyphs: Vec<PlacedGlyph>,
    pub rules: Vec<PlacedRule>,
    pub paths: Vec<PlacedPath>,
    pub width: f64,
    pub height: f64,
    pub depth: f64,
}

The final layout of a formula: flat positioned primitives plus overall metrics. Everything is in ems of the base size, y-up, baseline at 0; width spans the whole formula, height rises above the baseline, depth extends below it (a positive number).

Fields

glyphs: Vec<PlacedGlyph>

Every glyph, positioned.

rules: Vec<PlacedRule>

Every rule, positioned.

paths: Vec<PlacedPath>

Every drawn path, positioned.

width: f64

Total advance width, ems.

height: f64

Extent above the baseline, ems.

depth: f64

Extent below the baseline, ems (positive).

Implementations

impl Layout

pub fn select(&self, range: Span) -> Selection

The primitives whose spans are contained in range — the substring map (isolate / tex_to_color_map semantics).

pub fn select_touching(&self, range: Span) -> Selection

The primitives whose spans overlap range — the inspector’s hit-test semantics (what did this byte produce, in any part).

Trait Implementations

impl Clone for Layout

fn clone(&self) -> Layout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Layout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Layout

fn default() -> Layout

Returns the “default value” for a type.

impl PartialEq for Layout

fn eq(&self, other: &Layout) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
