Enum SpawnBeginError 

pub enum SpawnBeginError {
    AlreadyInProgress,
    BudgetExhausted {
        retry_after: Duration,
        remaining: u32,
    },
}

Errors returned when a spawn attempt cannot begin.

Variants

AlreadyInProgress

Another worker is already launching this backend key.

BudgetExhausted

The per-key spawn budget is exhausted.

Fields

retry_after: Duration

Time until the budget window resets.

remaining: u32

Remaining attempts, always zero for this variant.

Trait Implementations

impl Clone for SpawnBeginError

fn clone(&self) -> SpawnBeginError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpawnBeginError

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

Formats the value using the given formatter.

impl Display for SpawnBeginError

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

Formats the value using the given formatter.

impl Eq for SpawnBeginError

impl Error for SpawnBeginError

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 PartialEq for SpawnBeginError

fn eq(&self, other: &SpawnBeginError) -> 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.
