Enum Schedule 

pub enum Schedule {
    First,
    Startup,
    Run,
    Fixed(Duration),
    Shutdown,
    Last,
}

Schedule determines when a system runs during the app lifecycle

Variants

First

Runs before service workers spawn, blocks until complete (DB migrations, config validation)

Startup

Runs after service workers spawn, blocks until complete (cache warming via Client)

Run

Spawns as background task, runs until shutdown (event loops, long-running workers)

Fixed(Duration)

Spawns as background task, runs repeatedly on interval (metrics, health checks)

Shutdown

Runs when shutdown triggered, blocks until complete (flush buffers, save state)

Last

Runs after everything stopped, blocks until complete (final cleanup)

Trait Implementations

impl Clone for Schedule

fn clone(&self) -> Schedule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Schedule

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

Formats the value using the given formatter.

impl Hash for Schedule

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Schedule

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