Enum WorkflowStartError 

#[non_exhaustive]
pub enum WorkflowStartError {
    AlreadyStarted {
        run_id: Option<String>,
        source: Status,
    },
    PayloadConversion(PayloadConversionError),
    Rpc(Status),
}

Errors that can occur when starting a workflow.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AlreadyStarted

The workflow already exists.

Fields

run_id: Option<String>

Run ID of the already-started workflow if this was raised by the client.

source: Status

The original gRPC status from the server.

PayloadConversion(PayloadConversionError)

Error converting the input to a payload.

Rpc(Status)

An uncategorized rpc error from the server.

Trait Implementations

impl Debug for WorkflowStartError

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

Formats the value using the given formatter.

impl Display for WorkflowStartError

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

Formats the value using the given formatter.

impl Error for WorkflowStartError

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<PayloadConversionError> for WorkflowStartError

fn from(source: PayloadConversionError) -> Self

Converts to this type from the input type.

impl From<Status> for WorkflowStartError

fn from(source: Status) -> Self

Converts to this type from the input type.
