Struct SpawnError

pub struct SpawnError { /* private fields */ }

Errors returned by Executor::spawn.

Spawn errors should represent relatively rare scenarios. Currently, the two scenarios represented by SpawnError are:

• An executor being at capacity or full. As such, the executor is not able to accept a new future. This error state is expected to be transient.
• An executor has been shutdown and can no longer accept new futures. This error state is expected to be permanent.

Implementations

impl SpawnError

pub fn shutdown() -> Self

Return a new SpawnError reflecting a shutdown executor failure.

pub fn at_capacity() -> Self

Return a new SpawnError reflecting an executor at capacity failure.

pub fn is_shutdown(&self) -> bool

Returns true if the error reflects a shutdown executor failure.

pub fn is_at_capacity(&self) -> bool

Returns true if the error reflects an executor at capacity failure.

Trait Implementations

impl Debug for SpawnError

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

Formats the value using the given formatter.

impl Display for SpawnError

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

Formats the value using the given formatter.

impl Error for SpawnError

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

Returns the lower-level source of this error, if any.

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.
