Enum NodeRef 

pub enum NodeRef {
    Static(VariableId),
    Lagged {
        variable: VariableId,
        lag: Lag,
    },
    Context {
        variable: VariableId,
        environment: Option<EnvironmentId>,
    },
}

Stable node identity before dense indexing.

Variants

Static(VariableId)

Static graph node.

Lagged

Lagged temporal node (variable at t - lag).

Fields

variable: VariableId

Variable.

lag: Lag

Non-negative lag (0 = contemporaneous).

Context

Context-aware node.

Fields

variable: VariableId

Variable.

environment: Option<EnvironmentId>

Optional environment.

Implementations

impl NodeRef

pub const fn variable(self) -> VariableId

Variable id carried by this node reference.

pub const fn lag(self) -> Option<Lag>

Lag if this is a lagged node; None for static/context.
