Sequence of segments used for grid-fitting.

Fields

fpos: i16

Original, unscaled position in font units.

opos: i32

Original, scaled position.

pos: i32

Current position.

flags: TopoFlags

Edge flags.

dir: Direction

Edge direction.

blue_edge: Option<ScaledWidth>

Present if this is a blue edge.

blue_provenance: Option<BlueProvenance>

Retains which blue zone was selected and whether the overshoot position won so recorders can reproduce CVT references later.

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

pub fn original_position(&self) -> i16

Returns the original unscaled position in font units.

pub fn scaled_position(&self) -> i32

Returns the original scaled position.

pub fn position(&self) -> i32

Returns the hinted position.

pub fn flags(&self) -> TopoFlags

Returns flags that define the properties of the edge.

pub fn direction(&self) -> Direction

Returns the dominant direction of the edge.

pub fn blue_edge(&self) -> Option<ScaledWidth>

Returns the width of the captured blue zone.

pub fn blue_provenance(&self) -> Option<BlueProvenance>

Returns which blue zone was selected and whether the overshoot position won so recorders can reproduce CVT references later.

pub fn link_index(&self) -> Option<u16>

Returns the index of the linked edge.

pub fn serif_index(&self) -> Option<u16>

Returns the index of the associated serif edge.

pub fn scale(&self) -> i32

Returns the computed scale factor of the edge.

pub fn segment_indices(&self) -> (u16, u16)

Returns the indices of the first and last segments that define the edge.

Use Segment::next_in_edge_index to walk the segment list.

impl Edge

pub(crate) fn link<'a>(&self, edges: &'a [Edge]) -> Option<&'a Edge>

pub(crate) fn serif<'a>(&self, edges: &'a [Edge]) -> Option<&'a Edge>

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.
