Types

type Graph

type Graph map[string]Node

Graph is a simplified DAG keyed by node id.

func (Graph) FindByClassType

func (g Graph) FindByClassType(classType string) []NodeRef

FindByClassType returns all nodes matching the requested class type.

func (Graph) SortedNodeIDs

func (g Graph) SortedNodeIDs() []string

SortedNodeIDs returns graph keys in deterministic order.

func (Graph) Validate

func (g Graph) Validate() error

Validate ensures the graph has the minimum shape expected by the SDK.

type Node

type Node struct {
	ClassType string         `json:"class_type"`
	Inputs    map[string]any `json:"inputs,omitempty"`
}

Node is the simplified ComfyUI-compatible node payload.

func (Node) Input

func (n Node) Input(name string) (any, bool)

Input fetches a raw input value.

func (Node) IntInput

func (n Node) IntInput(name string) (int, bool)

IntInput extracts an integer-like input when present.

func (Node) StringInput

func (n Node) StringInput(name string) (string, bool)

StringInput extracts a string input when present.

type NodeRef

type NodeRef struct {
	ID   string
	Node Node
}

NodeRef preserves both the node id and the node payload.
