Enum Placement 

pub enum Placement {
    None,
    Distance(i32, i32),
    MarkAnchor(usize, Anchor, Anchor),
    MarkOverprint(usize),
    CursiveAnchor(usize, bool, Anchor, Anchor),
}

Adjustment to the placement of a glyph as a result of kerning and placement of an attachment relative to a base glyph.

Variants

None

Distance(i32, i32)

Placement offset by distance delta.

Fields (delta x, delta y)

MarkAnchor(usize, Anchor, Anchor)

An anchored mark.

This is a mark where its anchor is aligned with the base glyph anchor.

Fields: (base glyph index in Vec<Info>, base glyph anchor, mark anchor)

MarkOverprint(usize)

An overprint mark.

This mark is shown at the same position as the base glyph.

Fields: (base glyph index in Vec<Info>)

CursiveAnchor(usize, bool, Anchor, Anchor)

Cursive anchored placement.

Fields:

• exit glyph index in Vec<Info>,
• RIGHT_TO_LEFT flag from lookup table,
• exit glyph anchor,
• entry glyph anchor

Trait Implementations

impl Clone for Placement

fn clone(&self) -> Placement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Placement

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

Formats the value using the given formatter.

impl PartialEq for Placement

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Placement

impl Eq for Placement

impl StructuralPartialEq for Placement
