Reports service, definition, value, handler, and Flow-completion failures.

Match specific variants when recovery differs. Self::service_error extracts common gRPC metadata from every service-backed variant.

Variants

Service

A general Dex service or transport call failed.

Fields

service: ServiceError

Structured service failure.

FlowAlreadyStarted

Starting a Flow conflicted with an existing Flow ID.

Fields

service: ServiceError

Structured start-operation failure.

FlowNotFound

An operation requiring an existing Flow targeted an unknown ID.

Fields

service: ServiceError

Structured lookup failure.

FlowNotActive

An operation requiring an active Flow targeted a terminal or unknown ID.

Fields

service: ServiceError

Structured active-Flow failure.

WorkerInvocation

A Worker Step or RPC handler failed.

Fields

service: ServiceError

Outer Dex service failure.

worker: Box<WorkerError>

Original Worker-side failure metadata.

RpcLockConflict

A locking RPC could not acquire all requested Attribute locks.

Fields

service: ServiceError

Structured aborted-operation failure.

LongPollTimeout

A long-poll timeout elapsed without indicating a Flow failure.

Fields

service: ServiceError

Structured timeout failure.

FlowDefinition

A registered Flow, Step, RPC, or persistence definition is invalid.

Fields

message: String

Developer-actionable contract violation.

InvalidArgument

An SDK method received an invalid argument.

Fields

message: String

Developer-actionable argument violation.

ValueMapping

An application value could not be serialized or decoded.

Fields

message: String

Developer-actionable mapping failure.

InvalidStepResult

A Step returned a value that violates its handler contract.

Fields

flow_type: String

Flow type containing the Step.

step_type: String

Step type that returned the invalid value.

detail: String

Developer-actionable result violation.

Implementations

impl SdkError

pub fn service_error(&self) -> Option<&ServiceError>

Returns shared service metadata for service-backed variants.

Local definition, argument, mapping, and invalid-result errors return None.

Trait Implementations

impl Debug for SdkError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SdkError

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for SdkError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
