}

Construction rejection for a malformed workflow graph.

Variants

Empty

At least one step is required.

DuplicateStep

Step identity occurs more than once.

Fields

step: K

UnknownPrerequisite

One edge names an undefined prerequisite.

Fields

step: K

UnknownDependent

One edge names an undefined dependent.

Fields

step: K

SelfDependency

One edge depends upon itself.

Fields

step: K

Cycle

The dependency relation contains a cycle.

Trait Implementations

impl<K: Clone> Clone for WorkflowConfigError<K>

fn clone(&self) -> WorkflowConfigError<K>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K: Debug> Debug for WorkflowConfigError<K>

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

Formats the value using the given formatter.

impl<K> Display for WorkflowConfigError<K>

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

Formats the value using the given formatter.

impl<K> Error for WorkflowConfigError<K>

where Self: Debug + Display,

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<K: PartialEq> PartialEq for WorkflowConfigError<K>

fn eq(&self, other: &WorkflowConfigError<K>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
