Struct GraphProjectionDefinition 

pub struct GraphProjectionDefinition {
    pub name: String,
    pub relation_types: BTreeSet<RelationTypeId>,
    pub source_role: RoleId,
    pub target_role: RoleId,
}

Graph projection definition.

Graph projections materialize binary relations as CSR outgoing and CSC incoming arrays over canonical topology IDs.

Performance

Cloning is O(r) for r selected relation types plus the name length.

Fields

name: String

Unique projection name.

relation_types: BTreeSet<RelationTypeId>

Relation types visible as binary graph edges.

source_role: RoleId

Role identifying the source endpoint.

target_role: RoleId

Role identifying the target endpoint.

Trait Implementations

impl Clone for GraphProjectionDefinition

fn clone(&self) -> GraphProjectionDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphProjectionDefinition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GraphProjectionDefinition

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GraphProjectionDefinition

fn eq(&self, other: &GraphProjectionDefinition) -> 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 Serialize for GraphProjectionDefinition

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for GraphProjectionDefinition
