Types

type Capability 

type Capability struct {
	MediaTypes   []string // e.g. ["image", "video", "audio"]
	Models       []string
	Sizes        []string // e.g. ["1024x1024", "1280x720"]
	Voices       []string // supported voice identifiers for TTS engines
	MaxDuration  int      // max video/audio duration in seconds; 0 = not applicable
	SupportsSync bool
	SupportsPoll bool
}

Capability describes what an engine can do.

type ConfigField added in v0.9.0 

type ConfigField struct {
	Key         string `json:"key"`   // field identifier, e.g. "apiKey", "appId"
	Label       string `json:"label"` // human-readable label, e.g. "API Key"
	Type        string `json:"type"`  // "string", "secret", "url"
	Required    bool   `json:"required"`
	EnvVar      string `json:"envVar,omitempty"` // fallback environment variable name
	Description string `json:"description,omitempty"`
	Default     string `json:"default,omitempty"`
}

ConfigField describes a single configuration parameter for an engine provider. Engine packages expose a package-level ConfigSchema() []ConfigField function so that UIs can dynamically render configuration forms.

type Describer 

type Describer interface {
	Capabilities() Capability
}

Describer is an optional interface that engines can implement to advertise capabilities.

type Discoverer added in v0.7.0 

type Discoverer interface {
	ModelsByCapability() map[string][]string
}

Discoverer is a package-level interface for providers that can enumerate all known models grouped by capability (e.g. "image", "video", "tts"). Unlike Engine (per-instance), Discoverer is a static catalog of models the provider SDK knows how to handle.

type DryRunResult 

type DryRunResult struct {
	WillPoll      bool
	EstimatedTime string   // human-readable estimate, e.g. "30s-2m"
	Warnings      []string // potential issues with the request
}

DryRunResult is the outcome of a dry-run estimation.

type DryRunner 

type DryRunner interface {
	DryRun(graph workflow.Graph) (DryRunResult, error)
}

DryRunner is an optional interface for engines that support dry-run estimation.

type Engine 

type Engine interface {
	Execute(ctx context.Context, graph workflow.Graph) (Result, error)
}

Engine executes a workflow graph against a concrete backend.

type OutputKind 

type OutputKind int

OutputKind classifies the string returned by an engine. 

const (
	OutputUnknown OutputKind = iota
	OutputURL
	OutputDataURI
	OutputJSON
	OutputPlainText
)

func ClassifyOutput added in v0.8.0 

func ClassifyOutput(s string) OutputKind

ClassifyOutput heuristically classifies a raw output string.

type Result 

type Result struct {
	Value string
	Kind  OutputKind
}

Result is the structured output of Engine.Execute.

type Resumer added in v0.11.0 

type Resumer interface {
	Resume(ctx context.Context, remoteID string) (Result, error)
}

Resumer is an optional interface for engines that support resuming an already-submitted async task by its remote ID.
