type Context ¶

type Context struct {
	swf.TaskContext
	// contains filtered or unexported fields
}

func (c *Context) AddOutputArtifact(a swf.Artifact)

func (c *Context) InputArtifacts() []swf.Artifact

type ContextPatch ¶

type ContextPatch struct {
	// Job is a JSON merge patch applied to the job context (contextual.JobContext as JSON).
	Job map[string]any `json:"job,omitempty"`

	// Scopes patches local scoped data structures (e.g. sequence.<id>.outputs).
	Scopes []ScopePatch `json:"scopes,omitempty"`
}

ContextPatch is a persisted, replayable message that mutates template-visible context before the next task execution.

Semantics: - Job: JSON merge patch (RFC 7396-like) applied to contextual.JobContext (by JSON shape). - Scopes: patch step outputs in the currently-visible scoped containers (sequence/states).

Notes:

• We keep this intentionally JSON-shaped so callers can patch individual fields without requiring per-field pointer types.
• Null values in the patch delete keys from maps (for map-typed sections).

type OutputEnvelope ¶

type OutputEnvelope struct {
	Version int             `json:"v"`
	Kind    OutputKind      `json:"kind"`
	Payload json.RawMessage `json:"payload,omitempty"`
}

OutputEnvelope is a versioned wrapper for persisted task outputs.

We store outputs in an envelope so SWF cached chapters can safely carry non-task results (e.g. context patches) and workers can branch at replay time.

func NewOutputEnvelope(kind OutputKind, payload any) (OutputEnvelope, error)

func (e OutputEnvelope) DecodePayload(dst any) error

type OutputKind ¶

type OutputKind string

const (
	OutputKindActivityInvocationOutput OutputKind = "activity_output"
	OutputKindContextPatch             OutputKind = "context_patch"
)

type ScopePatch ¶

type ScopePatch struct {
	// Container selects which scope output map to patch.
	// Allowed: "sequence", "states".
	Container string `json:"container"`
	// ID is the step id within the container (e.g. node metadata id).
	ID string `json:"id"`

	// Outputs is a JSON merge patch applied to the step's outputs map.
	Outputs map[string]any `json:"outputs,omitempty"`
}
