pub enum SchedulerError {
    InvalidConfig(&'static str),
    InvalidTaskId,
    InvalidSchedule(&'static str),
    InvalidCron(String),
    DuplicateTask(String),
    CapacityExceeded {
        max_tasks: usize,
    },
    Shutdown,
    WorkerPanicked,
}

Controlled scheduler failure.

Variants

InvalidConfig(&'static str)

Scheduler configuration is invalid.

InvalidTaskId

Task identity is empty, too long or malformed.

InvalidSchedule(&'static str)

Task schedule or retry policy is invalid.

InvalidCron(String)

Cron expression could not be parsed.

DuplicateTask(String)

A task with the same identity already exists.

CapacityExceeded

Configured task capacity was reached.

Fields

max_tasks: usize

Maximum registered tasks.

Shutdown

Scheduler no longer accepts work after shutdown.

WorkerPanicked

Coordinator or worker thread panicked.

Trait Implementations

impl Eq for SchedulerError

impl Error for SchedulerError

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 SchedulerError

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

Equality operator ==.

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

Inequality operator !=.
