Required Methods§

Source

fn create(&mut self, node: Box<dyn Node>) -> NodeId

Source

fn get_mut(&mut self, id: NodeId) -> Result<&mut dyn Node, NodeError>

Source

fn remove(&mut self, id: NodeId) -> Result<(), NodeError>

Source

fn node_generation(&self, id: NodeId) -> u32

Returns the current generation for a node index. Generation is incremented when an index is reused from the freelist, preventing stale slot entries from matching recycled nodes.

Source

fn insert_with_id( &mut self, id: NodeId, node: Box<dyn Node>, ) -> Result<(), NodeError>

Inserts a node with a pre-assigned ID.

This is used for virtual nodes whose IDs are allocated separately (e.g., via allocate_virtual_node_id()). Unlike create() which assigns a new ID, this method uses the provided ID.

Returns Ok(()) if successful, or an error if the ID is already in use.

Provided Methods§

Source

fn insert_recycled_node_or_create( &mut self, stable_id: NodeId, node: Box<dyn Node>, ) -> RecycledNodeInsertion

Reinserts a recycled node at its retained stable ID, or creates a fresh ID if that retained ID is no longer available.

Source

fn as_any(&self) -> &dyn Any
where Self: Sized,

Source

fn as_any_mut(&mut self) -> &mut dyn Any
where Self: Sized,

Source

fn compact(&mut self)

Trim trailing tombstones/unused capacity after structural changes.

Source

fn take_recycled_node(&mut self, _key: TypeId) -> Option<RecycledNode>

Returns a previously recycled node shell and its stable ID for the requested concrete type.

Source

fn set_recycled_node_origin(&mut self, _id: NodeId, _warm_origin: bool)

Marks whether a reinserted recycled node originated from the warm recycle path.

Source

fn seed_recycled_node_shell( &mut self, _key: TypeId, _recycle_pool_limit: Option<usize>, _shell: Box<dyn Node>, )

Seeds a warm recyclable shell for future reuse without requiring a prior removal.

Source

fn record_fresh_recyclable_creation(&mut self, _key: TypeId)

Records that the current apply pass had to allocate a fresh recyclable shell for this type.

Source

fn clear_recycled_nodes(&mut self)

Drops any recyclable shells that should not survive beyond the current apply pass.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
