}

Errors produced during workflow construction (builder / hydration).

Variants

DuplicateTaskId(String)

A duplicate task ID was found during workflow building.

TaskNotFound(String)

A referenced task ID was not found in the registry.

EmptyBranch

A branch closure produced an empty sub-builder (no steps added).

EmptyFork

A fork has no branches.

MissingBranches

One or more declared branch keys have no corresponding .branch() call and no default branch was provided.

Fields

branch_id: String

The route node ID.

missing_keys: Vec<String>

Keys declared in BranchKey::all_keys() with no matching branch.

OrphanBranches

One or more .branch() calls use keys not declared in the BranchKey enum.

Fields

branch_id: String

The route node ID.

orphan_keys: Vec<String>

Keys passed to .branch() that are not in BranchKey::all_keys().

InvalidMaxIterations(String)

A loop’s max_iterations was set to zero.

EmptyWorkflow

The workflow has no tasks.

InvalidDuration(String)

A duration value is not finite or is negative.

DefinitionMismatch

The workflow definition hash doesn’t match during hydration.

Fields

expected: String

The expected hash (from current workflow).

found: String

The hash found in the serialized state.

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> BuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

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<BuildError> for BuildErrors

fn from(error: BuildError) -> Self

Converts to this type from the input type.
