Enum anchors::singlethread::ObservedState

pub enum ObservedState {
    Observed,
    Necessary,
    Unnecessary,
}

Indicates whether the node is a part of some observed calculation.

Variants

Observed

The node has been marked as observed directly via mark_observed.

Necessary

The node is not marked as observed directly. However, the node has some descendent that is Observed, and this node has been recalculated since that descendent become Observed.

Unnecessary

The node is not marked as observed directly. Additionally, this node either has no Observed descendent, or the chain linking this node to that Observed descendent has not been recalculated since that dencendent become observed.
