Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PollError(BoxDynError)

Graph service poll error.

MissingPreviousNode

Missing previous node

MissingFaninHandler

Missing Fanin Handler

MissingNextNode

Missing next node

MissingIncomingTaskId

Missing TaskId for incoming node

MissingTaskIdResult(String)

Missing result for TaskId

InvalidFanInDependencyResult

Dependency task returned invalid response, which is unexpected during fan-in

DependencyTaskFailed(BoxDynError)

Dependency task failed

Codec(BoxDynError)

An error related to codec operations.

Trait Implementations

impl Debug for GraphServiceError

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

Formats the value using the given formatter.

impl Display for GraphServiceError

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

Formats the value using the given formatter.

impl Error for GraphServiceError

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.

impl From<GraphServiceError> for GraphFlowError

fn from(source: GraphServiceError) -> Self

Converts to this type from the input type.
