Types

type Invariant

type Invariant interface {
	Check(context.Context) ([]InvariantCheckResult, error)
	RootCause(context.Context, []InvariantCheckResult) ([]InvariantRootCauseResult, error)
}

Invariant represents a condition of a workflow execution.

type InvariantCheckResult

type InvariantCheckResult struct {
	InvariantType string
	Reason        string
	Metadata      []byte
}

InvariantCheckResult is the result from the invariant check

type InvariantRootCauseResult

type InvariantRootCauseResult struct {
	RootCause RootCause
	Metadata  []byte
}

InvariantRootCauseResult is the root cause for the issues identified in the invariant check

type RootCause

type RootCause string

	RootCauseTypeHeartBeatingEnabledMissingHeartbeat   RootCause = "Heartbeat timeout enabled for activity but timed out due to missing heartbeat"
