Enum StartError 

#[non_exhaustive]
pub enum StartError {
    InvalidConfiguration(ConfigurationError),
    OperationIdExhausted,
    Delivery(DeliveryError),
}

Failure before a usable progress operation can be returned.

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.

InvalidConfiguration(ConfigurationError)

Fixed operation metadata is invalid.

OperationIdExhausted

The process-local operation ID space is exhausted.

Delivery(DeliveryError)

Started was attempted but rejected by the reporter.

Trait Implementations

impl Clone for StartError

fn clone(&self) -> StartError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StartError

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

Formats the value using the given formatter.

impl Display for StartError

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

Formats the start failure.

impl Error for StartError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the nested configuration or delivery failure.

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<ConfigurationError> for StartError

fn from(error: ConfigurationError) -> Self

Converts configuration validation into a start failure.

impl From<EmissionError> for StartError

fn from(error: EmissionError) -> Self

Converts the only possible start-time emission failures.
