Fields

fpos: i16

Original, unscaled position in font units.

opos: i32

Original, scaled position.

pos: i32

Current position.

flags: u8

Edge flags.

dir: Direction

Edge direction.

Present if this is a blue edge.

link_ix: Option<u16>

Index of linked edge.

serif_ix: Option<u16>

Index of primary edge for serif.

scale: i32

Used to speed up edge interpolation.

first_ix: u16

Index of first segment in edge.

last_ix: u16

Index of last segment in edge.

Implementations

impl Edge

Edge flags.

Note: these are the same as segment flags.

Trait Implementations

impl Clone for Edge

fn clone(&self) -> Edge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Edge

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

Formats the value using the given formatter.

impl Default for Edge

fn default() -> Edge

Returns the “default value” for a type.

impl PartialEq for Edge

fn eq(&self, other: &Edge) -> 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 Edge

impl Eq for Edge

impl StructuralPartialEq for Edge
