Compilation(CompilationError)

FlowSpec compilation failed (includes validation failures).

Bootstrap(BootstrapError)

ActionQueue engine bootstrap failed.

Engine(EngineError)

ActionQueue engine error during operation.

ContextStore(ContextStoreError)

ContextStore error.

FlowRunNotFound(FlowRunId)

FlowRun not found.

ConnectorNotFound(String)

Fields

flow_run_id: FlowRunId

error: String

FlowCanceled(FlowRunId)

Flow was canceled.

Io(Error)

I/O error (creating directories, etc.)

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.
