Struct GraphNodeConstructorContainer

pub struct GraphNodeConstructorContainer<Node, Ctx> { /* private fields */ }

A special container that is able to create nodes by their type UUID.

Implementations

impl<Node, Ctx> GraphNodeConstructorContainer<Node, Ctx>

pub fn add<Inner>(&self)

where Inner: ConstructorProvider<Node, Ctx>,

Adds new type constructor for a given type and return previous constructor for the type (if any).

pub fn add_custom( &self, type_uuid: Uuid, constructor: GraphNodeConstructor<Node, Ctx>, )

Adds custom type constructor.

pub fn remove(&self, type_uuid: Uuid)

Unregisters type constructor.

pub fn try_create(&self, type_uuid: &Uuid) -> Option<Node>

Makes an attempt to create a node using provided type UUID. It may fail if there is no node constructor for specified type UUID.

pub fn len(&self) -> usize

Returns total amount of constructors.

pub fn is_empty(&self) -> bool

Returns true if the container is empty.

pub fn map( &self, ) -> MutexGuard<'_, RawMutex, HashMap<Uuid, GraphNodeConstructor<Node, Ctx>, BuildHasherDefault<FxHasher>>>

Returns the inner map of the node constructors.
