Implementations

impl Segment

pub fn flags(&self) -> TopoFlags

Returns flags describing the properties of the segment.

pub fn direction(&self) -> Direction

Returns the dominant direction of the segment.

pub fn position(&self) -> i16

Returns the computed position of the segment.

pub fn delta(&self) -> i16

Returns the deviation from the computed position.

pub fn min_coord(&self) -> i16

Returns the minimum coordinate of the segment.

pub fn max_coord(&self) -> i16

Returns the maximum coordinate of the segment.

pub fn height(&self) -> i16

Returns the hinted height of the segment.

pub fn score(&self) -> i32

Returns the computed score of the segment; used during stem matching.

pub fn length(&self) -> i32

Returns the computed length of the segment; used during stem matching.

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

Returns the index of the best candidate for a stem link.

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

Returns the index of the best candidate for a serif link.

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

Returns the indices of first and last points that define the segment.

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

Returns the index of edge that is associated with the segment.

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

Returns the index of next segment in the associated edge’s segment list.

impl Segment

pub(crate) fn first(&self) -> usize

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

pub(crate) fn last(&self) -> usize

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

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

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

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

pub(crate) 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.
