Why a spec could not be hosted.

Variants

Parse(SpecError)

Workflow spec failed to parse.

NoBranch

Workflow spec ‘spec_id’ has no branches.

Fields

spec_id: String

Spec id.

Safety

Workflow spec ‘spec_id’ violates safety rules: violations.

Fields

spec_id: String

Spec that failed.

violations: Vec<Violation>

Safety rules violated.

Compile

Workflow spec ‘spec_id’ failed to compile: source.

Fields

spec_id: String

Spec that failed.

source: CompileError

Compile error.

UnsupportedDurableStep

A step performs an external effect; durable spec execution runs pure/read steps only.

Fields

spec_id: String

Spec that failed.

node_id: String

Node that cannot run durably.

node_type: String

Its node type.

Schedule

Workflow spec ‘spec_id’ has an invalid schedule: reason.

Fields

spec_id: String

Spec id.

reason: String

Why the schedule is invalid.

Trait Implementations

impl Debug for HostError

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

Formats the value using the given formatter.

impl Display for HostError

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

Formats the value using the given formatter.

impl Error for HostError

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<SpecError> for HostError

fn from(source: SpecError) -> Self

Converts to this type from the input type.
