Available on non-WebAssembly only.

Errors that can occur during workflow construction and execution

Variants

UnknownBinding

A step references a binding that hasn’t been defined yet

Fields

step: String

The step that has the invalid reference

binding: String

The binding name that was not found

MissingTool

A workflow requires a tool that is not registered

Fields

workflow: String

The workflow that requires the tool

tool: String

The tool name that was not found

MissingResource

A workflow requires a resource that is not registered

Fields

workflow: String

The workflow that requires the resource

resource: String

The resource URI that was not found

CircularDependency

Steps have circular dependencies that prevent execution

Fields

cycle: String

Description of the circular dependency

InvalidMapping

Invalid argument mapping in a workflow step

Fields

step: String

The step with invalid mapping

reason: String

Why the mapping is invalid

InvalidUri

A resource URI is not in a valid format

Fields

uri: String

The invalid URI

MissingField

A workflow is missing a required field

Fields

workflow: String

The workflow that is missing the field

field: &'static str

The name of the missing field

OutputFieldNotFound

A step’s output field could not be found

Fields

step: String

The step whose output was queried

field: String

The field that was not found

Other(Box<dyn Error + Send + Sync>)

A wrapped error from another part of the system

Trait Implementations

impl Debug for WorkflowError

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

Formats the value using the given formatter.

impl Display for WorkflowError

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

Formats the value using the given formatter.

impl Error for WorkflowError

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<Box<dyn Error + Sync + Send>> for WorkflowError

fn from(source: Box<dyn Error + Send + Sync>) -> Self

Converts to this type from the input type.

impl From<Error> for WorkflowError

fn from(err: Error) -> Self

Converts to this type from the input type.
