Struct Relation 

pub struct Relation {
    pub id: u64,
    /* private fields */
}

Relation class contains a collection of nodes, ways and relations as members.

Fields

id: u64

The relation’s id

Implementations

impl Relation

pub fn properties(&self, pb: &PrimitiveBlock) -> Properties

Get the properties of the node

pub fn members(&self, pb: &PrimitiveBlock) -> Vec<IntermediateMember>

Each member can be node, way or relation.

pub fn to_intermediate_feature( &self, pb: &PrimitiveBlock, ) -> Option<IntermediateRelation>

returns the feature in intermediate format to build later

pub fn get_node_relation_pairs( members: &[IntermediateMember], ) -> Vec<IntermediateNodeMember>

Get the node relation pairs

Trait Implementations

impl Debug for Relation

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

Formats the value using the given formatter.

impl Default for Relation

fn default() -> Relation

Returns the “default value” for a type.

impl OSMFilterable for Relation

fn is_filterable<T: Reader, _N: KVStore<u64, VectorPoint<MValue>>, N: KVStore<u64, IntermediateNode>, _W: KVStore<u64, WayNodes>, W: KVStore<u64, IntermediateWay>, R: KVStore<u64, IntermediateRelation>>( &self, pb: &PrimitiveBlock, reader: &mut OSMReader<T, _N, N, _W, W, R>, ) -> bool

Check if the object is filterable

impl PartialEq for Relation

fn eq(&self, other: &Relation) -> 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 ProtoRead for Relation

Read in the contents of the relation

fn read(&mut self, tag: u64, pb: &mut Protobuf)

The read method is used to read a field from a protobuf message. The tag parameter is used to determine which field to read into the struct. The pbf parameter is used to read the data in the appropriate format.
