Struct Node 

pub struct Node {
    pub id: NodeId,
    pub label: String,
    pub kind: NodeKind,
    pub target: Option<String>,
}

A node in the computational graph.

Fields

id: NodeId

Unique id within the graph; edges and trained states refer to it.

label: String

Human-readable name shown in diagrams; cosmetic, excluded from the architecture fingerprint.

kind: NodeKind

What kind of computation this node represents.

target: Option<String>

Execution target: “local” (reserved, always local), or a worker tag. None means: use default (remote if workers available, else local).

Implementations

impl Node

pub fn new( id: impl Into<String>, label: impl Into<String>, filter_name: impl Into<String>, ) -> Self

Create a filter node (backward-compatible with old 3-arg constructor).

pub fn filter_with_id( id: impl Into<String>, filter_name: impl Into<String>, ) -> Self

Create a filter node with explicit id and filter_name.

pub fn filter(filter_name: impl Into<String>) -> Self

Create a filter node where id defaults to filter_name.

pub fn subgraph(id: impl Into<String>, graph: Graph) -> Self

Create a sub-graph node.

pub fn loop_node(id: impl Into<String>, max_iterations: Option<usize>) -> Self

Create a loop node whose stop condition is its body’s terminal node.

pub fn loop_until( id: impl Into<String>, max_iterations: Option<usize>, until: LoopCondition, ) -> Self

Create a loop node with an explicit stop condition.

pub fn step(id: impl Into<String>, step_name: impl Into<String>) -> Self

Create an effectful step node.

pub fn branch(id: impl Into<String>) -> Self

Create a branch node whose arms are inferred from its control edges.

pub fn branch_over( id: impl Into<String>, arms: impl IntoIterator<Item = impl Into<String>>, ) -> Self

Create a branch node declaring the labels its condition may produce.

The compiler then checks the edges against this list in both directions: a declared arm with no edge, or an edge labelling an arm that was never declared, is a compile error rather than a branch that silently never fires.

pub fn with_target(self, target: impl Into<String>) -> Self

Set the execution target for this node.

pub fn is_local(&self) -> bool

Whether this node is forced local.

pub fn filter_name(&self) -> Option<&str>

Get the filter name if this is a Filter node.
