pub enum DrainError {
    NotActive {
        current: LifecycleState,
    },
    UnexpectedTransition {
        reached: LifecycleState,
    },
    Timeout {
        waited: Duration,
        strong_count: usize,
    },
}

Drain operation errors.

Variants

NotActive

Trait Implementations

impl Debug for DrainError

Formats the value using the given formatter.

impl Display for DrainError

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

impl Error for DrainError

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)
