Overview

Package luma implements engine.Engine for the Luma Dream Machine API.

Both video and image generation are async: POST /dream-machine/v1/generations creates a task, GET /dream-machine/v1/generations/{id} polls for completion. Auth: Authorization: Bearer {key}, env LUMA_API_KEY.

Functions

func ConfigSchema

func ConfigSchema() []engine.ConfigField

ConfigSchema returns the configuration fields required by the Luma engine.

func ModelsByCapability

func ModelsByCapability() map[string][]string

ModelsByCapability returns all known Luma models grouped by capability.

Types

type Config

type Config struct {
	APIKey            string
	BaseURL           string
	Model             string
	HTTPClient        *http.Client
	WaitForCompletion bool
	PollInterval      time.Duration
	OnProgress        epoll.OnProgress
}

Config configures the Luma engine.

type Engine

type Engine struct {
	// contains filtered or unexported fields
}

Engine implements engine.Engine for Luma.

func New

func New(cfg Config) *Engine

New creates a Luma engine instance.

func (*Engine) Capabilities

func (e *Engine) Capabilities() engine.Capability

Capabilities implements engine.Describer.

func (*Engine) Execute

func (e *Engine) Execute(ctx context.Context, g workflow.Graph) (engine.Result, error)

Execute generates a video or image via the Luma API.

func (*Engine) Resume

func (e *Engine) Resume(ctx context.Context, remoteID string) (engine.Result, error)

Resume implements engine.Resumer — resumes polling a previously submitted task.
