Struct StartupCoordinator 

pub struct StartupCoordinator { /* private fields */ }

Ordered startup phase coordinator.

The coordinator owns phase ordering, failure policy handling, duration collection, and tracing. Product crates provide closures for the actual startup work and decide how to map report data into their own diagnostics or admin surfaces.

Implementations

impl StartupCoordinator

pub fn new() -> Self

Creates an empty startup coordinator.

pub fn required<F, Fut>(&mut self, name: &'static str, phase: F) -> &mut Self

where F: FnMut() -> Fut + Send + 'static, Fut: Future<Output = Result<(), String>> + Send + 'static,

Registers a required startup phase.

pub fn optional<F, Fut>(&mut self, name: &'static str, phase: F) -> &mut Self

where F: FnMut() -> Fut + Send + 'static, Fut: Future<Output = Result<(), String>> + Send + 'static,

Registers an optional startup phase.

pub fn phase<F, Fut>( &mut self, name: &'static str, failure_policy: StartupPhaseFailurePolicy, phase: F, ) -> &mut Self

where F: FnMut() -> Fut + Send + 'static, Fut: Future<Output = Result<(), String>> + Send + 'static,

Registers a startup phase with an explicit failure policy.

pub async fn run(&mut self) -> StartupReport

Runs registered phases in order.

Required phase failures stop later phases. Optional phase failures are logged and included in the report while later phases continue.

pub fn len(&self) -> usize

Returns how many phases are registered.

pub fn is_empty(&self) -> bool

Returns whether no phases are registered.

Trait Implementations

impl Default for StartupCoordinator

fn default() -> StartupCoordinator
