Struct SnapshotServerObject 

pub struct SnapshotServerObject(/* private fields */);

The server object a reference parameter refers to, held weakly.

Upstream the snapshot holds the server object, and the garbage collector reclaims two animations that refer to each other’s targets. Here the animations of an object hold its instances, and an instance holds its parameters, so a strong reference would form a cycle between two such objects; the snapshot holds the object weakly, as the instance holds its target. The object outlives its disposal while its composition object is alive, so the reference goes dead only once nothing refers to the object any more; a dead reference is read as a parameter without an object.

Implementations

impl SnapshotServerObject

pub fn upgrade(&self) -> Option<Rc<dyn IAnimatedServerObject>>

The server object, while it is alive.

Trait Implementations

impl IExpressionObject for SnapshotServerObject

fn get_property(&self, name: &str) -> ExpressionVariant

Gets the value of the property with the given name; Invalid when there is no such property.

fn key(&self) -> ExpressionObjectKey

The identity of the object, used to track the objects an expression depends on (see ExpressionTrackedObjects). The default is the address of the object, which is its reference identity for as long as the object is alive and not moved; an implementation that has a stable identifier should return that instead.
