Fields

flags: u8

Flags describing the properties of the segment.

dir: Direction

Dominant direction of the segment.

pos: i16

Position of the segment.

delta: i16

Deviation from segment position.

min_coord: i16

Minimum coordinate of the segment.

max_coord: i16

Maximum coordinate of the segment.

height: i16

Hinted segment height.

score: i32

Used during stem matching.

len: i32

Used during stem matching.

link_ix: Option<u16>

Index of best candidate for a stem link.

serif_ix: Option<u16>

Index of best candidate for a serif link.

first_ix: u16

Index of first point in the outline.

last_ix: u16

Index of last point in the outline.

edge_ix: Option<u16>

Index of edge that is associated with the segment.

edge_next_ix: Option<u16>

Index of next segment in edge’s segment list.

Implementations

impl Segment

Segment flags.

Note: these are the same as edge flags.

pub const NEUTRAL: u8 = 8u8

impl Segment

pub fn first(&self) -> usize

pub fn first_point<'a>(&self, points: &'a [Point]) -> &'a Point

pub fn last(&self) -> usize

pub fn last_point<'a>(&self, points: &'a [Point]) -> &'a Point

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

pub fn next_in_edge<'a>(&self, segments: &'a [Segment]) -> Option<&'a Segment>

Returns the next segment in this segment’s parent edge.

pub fn link<'a>(&self, segments: &'a [Segment]) -> Option<&'a Segment>

Trait Implementations

impl Clone for Segment

fn clone(&self) -> Segment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Segment

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

Formats the value using the given formatter.

impl Default for Segment

fn default() -> Segment

Returns the “default value” for a type.

impl PartialEq for Segment

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

impl Eq for Segment

impl StructuralPartialEq for Segment
