Struct DepartStore 

pub struct DepartStore { /* private fields */ }

The departing subtrees, bounded (see MAX_NODES).

Implementations

impl DepartStore

pub fn animating(&self) -> bool

True when a ghost replayed this frame is still mid-flight, i.e. the driver owes another frame.

pub fn is_empty(&self) -> bool

Whether anything is departing at all — the gate every pass that would otherwise walk an empty store checks first.

pub fn node_count(&self) -> usize

How many nodes are retained across every departing subtree.

pub fn keys(&self) -> impl Iterator<Item = Key>

The keys of the departing roots — what a caller tests the live tree against to notice one coming back.

pub fn clear(&mut self)

Drops every ghost. The frame driver has no reason to; a test that wants a clean slate does.

Trait Implementations

impl Default for DepartStore

fn default() -> DepartStore

Returns the “default value” for a type.
