Struct Node 

pub struct Node {
    pub id: NodeId,
    pub verb: Symbol,
    pub inputs: Vec<Port>,
    pub outputs: Vec<Port>,
    pub target: Option<Expr>,
    pub role: Option<Symbol>,
    pub input: Option<Expr>,
    pub output: Option<Expr>,
    pub options: Vec<(Symbol, Expr)>,
}

A topology graph step with named input and output ports.

Fields

id: NodeId

Node id unique within the graph.

verb: Symbol

Generic node verb, such as in, out, call, or wire.

inputs: Vec<Port>

Canonical in ports.

outputs: Vec<Port>

Canonical out ports.

target: Option<Expr>

Optional runtime target value expression.

role: Option<Symbol>

Optional role tag used by frame-aware targets.

input: Option<Expr>

Optional node input shape expression.

output: Option<Expr>

Optional node output shape expression.

options: Vec<(Symbol, Expr)>

Node options preserved from graph data.

Implementations

impl Node

pub fn new(id: impl Into<NodeId>, verb: Symbol) -> Self

Creates a node with default ports for the provided verb.

pub fn named(id: impl Into<NodeId>, verb: impl Into<String>) -> Self

Creates a node from an unqualified verb name.

pub fn with_ports( id: impl Into<NodeId>, verb: Symbol, inputs: Vec<Port>, outputs: Vec<Port>, ) -> Self

Creates a node with explicitly declared ports.

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Node

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
