var MetricsNopHandler = metrics.NopHandler

MetricsNopHandler is a noop handler that does nothing with the metrics.

Functions

func HistoryFromJSON added in v1.16.0

func HistoryFromJSON(r io.Reader, options HistoryJSONOptions) (*historypb.History, error)

HistoryFromJSON deserializes history from a reader of JSON bytes. This does not close the reader if it is closeable.

func NewValue

func NewValue(data *commonpb.Payloads) converter.EncodedValue

NewValue creates a new converter.EncodedValue which can be used to decode binary data returned by Temporal. For example: User had Activity.RecordHeartbeat(ctx, "my-heartbeat") and then got response from calling Client.DescribeWorkflowExecution. The response contains binary field PendingActivityInfo.HeartbeatDetails, which can be decoded by using:

var result string // This need to be same type as the one passed to RecordHeartbeat
NewValue(data).Get(&result)

func NewValues

func NewValues(data *commonpb.Payloads) converter.EncodedValues

NewValues creates a new converter.EncodedValues which can be used to decode binary data returned by Temporal. For example: User had Activity.RecordHeartbeat(ctx, "my-heartbeat", 123) and then got response from calling Client.DescribeWorkflowExecution. The response contains binary field PendingActivityInfo.HeartbeatDetails, which can be decoded by using:

var result1 string
var result2 int // These need to be same type as those arguments passed to RecordHeartbeat
NewValues(data).Get(&result1, &result2)

func NewWorkflowServiceProxyServer added in v1.14.0

func NewWorkflowServiceProxyServer(options WorkflowServiceProxyOptions) (workflowservice.WorkflowServiceServer, error)

NewWorkflowServiceProxyServer creates a WorkflowServiceServer suitable for registering with a GRPC Server. Requests will be forwarded to the passed in WorkflowService Client. GRPC interceptors can be added on the Server or Client to adjust requests and responses.

Types

type BuildIDOpAddNewCompatibleVersion added in v1.23.0

type BuildIDOpAddNewCompatibleVersion = internal.BuildIDOpAddNewCompatibleVersion

BuildIDOpAddNewCompatibleVersion is an operation for UpdateWorkerBuildIdCompatibilityOptions to add a new BuildID to an existing compatible set. Deprecated: Replaced by the new worker versioning api.

type BuildIDOpAddNewIDInNewDefaultSet added in v1.23.0

type BuildIDOpAddNewIDInNewDefaultSet = internal.BuildIDOpAddNewIDInNewDefaultSet

BuildIDOpAddNewIDInNewDefaultSet is an operation for UpdateWorkerBuildIdCompatibilityOptions to add a new BuildID in a new default set. Deprecated: Replaced by the new worker versioning api.

type BuildIDOpPromoteIDWithinSet added in v1.23.0

type BuildIDOpPromoteIDWithinSet = internal.BuildIDOpPromoteIDWithinSet

BuildIDOpPromoteIDWithinSet is an operation for UpdateWorkerBuildIdCompatibilityOptions to promote a BuildID within a set to be the default. Deprecated: Replaced by the new worker versioning api.

type BuildIDOpPromoteSet added in v1.23.0

type BuildIDOpPromoteSet = internal.BuildIDOpPromoteSet

BuildIDOpPromoteSet is an operation for UpdateWorkerBuildIdCompatibilityOptions to promote a set to be the default set by targeting an existing BuildID. Deprecated: Replaced by the new worker versioning api.

type BuildIDReachability added in v1.25.0

type BuildIDReachability = internal.BuildIDReachability

BuildIDReachability describes the reachability of a buildID Deprecated: Replaced by the new worker versioning api.

type BuildIDTaskReachability added in v1.27.0

type BuildIDTaskReachability = internal.BuildIDTaskReachability

BuildIDTaskReachability specifies which category of tasks may reach a versioned worker of a certain Build ID. Note: future activities who inherit their workflow's Build ID but not its task queue will not be accounted for reachability as server cannot know if they'll happen as they do not use assignment rules of their task queue. Same goes for Child Workflows or Continue-As-New Workflows who inherit the parent/previous workflow's Build ID but not its task queue. In those cases, make sure to query reachability for the parent/previous workflow's task queue as well. WARNING: Worker versioning is currently experimental

type CheckHealthRequest added in v1.15.0

type CheckHealthRequest = internal.CheckHealthRequest

CheckHealthRequest is a request for Client.CheckHealth.

type CheckHealthResponse added in v1.15.0

type CheckHealthResponse = internal.CheckHealthResponse

CheckHealthResponse is a response for Client.CheckHealth.

func Dial added in v1.15.0

func Dial(options Options) (Client, error)

Dial creates an instance of a workflow client. This will attempt to connect to the server eagerly and will return an error if the server is not available.

func DialContext added in v1.26.1

func DialContext(ctx context.Context, options Options) (Client, error)

DialContext creates an instance of a workflow client. This will attempt to connect to the server eagerly and will return an error if the server is not available. Connection will respect provided context deadlines and cancellations.

func NewClient deprecated

func NewClient(options Options) (Client, error)

NewClient creates an instance of a workflow client. This will attempt to connect to the server eagerly and will return an error if the server is not available.

Deprecated: Use Dial or NewLazyClient instead.

func NewClientFromExisting added in v1.17.0

func NewClientFromExisting(existingClient Client, options Options) (Client, error)

NewClientFromExisting creates a new client using the same connection as the existing client. This means all options.ConnectionOptions are ignored and options.HostPort is ignored. The existing client must have been created from this package and cannot be wrapped. Currently, this always attempts an eager connection even if the existing client was created with NewLazyClient and has not made any calls yet.

Close() on the resulting client may not necessarily close the underlying connection if there are any other clients using the connection. All clients associated with the existing client must call Close() and only the last one actually performs the connection close.

func NewClientFromExistingWithContext added in v1.26.1

func NewClientFromExistingWithContext(ctx context.Context, existingClient Client, options Options) (Client, error)

NewClientFromExistingWithContext creates a new client using the same connection as the existing client. This means all options.ConnectionOptions are ignored and options.HostPort is ignored. The existing client must have been created from this package and cannot be wrapped. Currently, this always attempts an eager connection even if the existing client was created with NewLazyClient and has not made any calls yet.

Close() on the resulting client may not necessarily close the underlying connection if there are any other clients using the connection. All clients associated with the existing client must call Close() and only the last one actually performs the connection close.

func NewLazyClient added in v1.15.0

func NewLazyClient(options Options) (Client, error)

NewLazyClient creates an instance of a workflow client. Unlike Dial, this will not eagerly connect to the server.

type ConnectionOptions

type ConnectionOptions = internal.ConnectionOptions

type Credentials added in v1.26.0

type Credentials = internal.Credentials

Credentials are optional credentials that can be specified in ClientOptions.

func NewAPIKeyDynamicCredentials added in v1.26.0

func NewAPIKeyDynamicCredentials(apiKeyCallback func(context.Context) (string, error)) Credentials

NewAPIKeyDynamicCredentials creates credentials powered by a callback that is invoked on each request. The callback accepts the context that is given by the calling user and can return a key or an error. When error is non-nil, the client call is failed with that error. When string is non-empty, it is used as the API key. When string is empty, nothing is set/overridden.

This is the equivalent of providing a headers provider that returns the "Authorization" header with "Bearer " + the given function result. If the resulting string is non-empty, it will overwrite any "Authorization" header that may be on the context or from existing header provider.

func NewAPIKeyStaticCredentials added in v1.26.0

func NewAPIKeyStaticCredentials(apiKey string) Credentials

NewAPIKeyStaticCredentials creates credentials that can be provided to ClientOptions to use a fixed API key.

This is the equivalent of providing a headers provider that sets the "Authorization" header with "Bearer " + the given key. This will overwrite any "Authorization" header that may be on the context or from existing header provider.

Note, this uses a fixed header value for authentication. Many users that want to rotate this value without reconnecting should use NewAPIKeyDynamicCredentials.

func NewMTLSCredentials added in v1.26.0

func NewMTLSCredentials(certificate tls.Certificate) Credentials

NewMTLSCredentials creates credentials that use TLS with the client certificate as the given one. If the client options do not already enable TLS, this enables it. If the client options' TLS configuration is present and already has a client certificate, client creation will fail when applying these credentials.
