Enum SpawnError 

#[non_exhaustive]
pub enum SpawnError {
    ReservedName(String),
    DuplicateName(String),
    StoreNotConfigured,
    State(StateError),
}

Errors from task spawn operations.

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.

ReservedName(String)

The name is reserved by the system.

DuplicateName(String)

Another running task on this thread already has this name.

StoreNotConfigured

No state store has been configured for the manager.

State(StateError)

Commit to the state store failed.

Trait Implementations

impl Clone for SpawnError

fn clone(&self) -> SpawnError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpawnError

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

Formats the value using the given formatter.

impl Display for SpawnError

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

Formats the value using the given formatter.

impl Error for SpawnError

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<MetaCommitError> for SpawnError

fn from(err: MetaCommitError) -> SpawnError

Converts to this type from the input type.

impl From<StateError> for SpawnError

fn from(source: StateError) -> SpawnError

Converts to this type from the input type.

impl PartialEq for SpawnError

fn eq(&self, other: &SpawnError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
