Struct TaggedRing 

pub struct TaggedRing {
    pub points: Vec<Point>,
    pub tags: Vec<u64>,
}

A ring whose edges carry user tags (see the provenance section).

tags[i] is the tag of the edge from points[i] to points[(i + 1) % n]. A vertex points[i] therefore sits between the edges tagged tags[i - 1] and tags[i]; when the two differ, the vertex is where two source edges meet (often a new intersection vertex).

Fields

points: Vec<Point>

Vertices, as in Ring.

tags: Vec<u64>

One tag per edge; same length as points.

Implementations

impl TaggedRing

pub fn uniform(ring: impl Into<Ring>, tag: u64) -> Self

Builds a tagged ring giving every edge the same tag.

pub fn into_ring(self) -> Ring

Drops the tags.

Trait Implementations

impl Clone for TaggedRing

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaggedRing

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

Formats the value using the given formatter.

impl Default for TaggedRing

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TaggedRing

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TaggedRing

impl Hash for TaggedRing

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TaggedRing

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

Equality operator ==.

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

Inequality operator !=.

impl RingSource for TaggedRing

fn visit_rings(&self, f: &mut VertexVisitor<'_>)

Calls f(points, tags) for every ring. tags, when present, has one tag per edge.

fn visit_polygons<'a>(&'a self, _f: &mut dyn FnMut(&'a Polygon)) -> bool

When the source is made only of Polygons (untagged), calls f on each and returns true; otherwise returns false (possibly after some calls). Lets operations detect already canonical input and skip re-normalizing it.

impl Serialize for TaggedRing

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
