Struct ShutdownCoordinator 

pub struct ShutdownCoordinator { /* private fields */ }

Ordered shutdown phase coordinator.

The coordinator owns phase ordering, timeout handling, duration collection, and error aggregation. Product crates provide the actual phase closures. Phases are FnMut so shutdown code can move owned handles into the coordinator and consume them exactly once during the shutdown run.

Implementations

impl ShutdownCoordinator

pub fn new() -> Self

Creates an empty shutdown coordinator.

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

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

Registers a shutdown phase.

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

Runs phases sequentially and returns a report.

Later phases still run when an earlier phase fails. This lets product shutdown code make best-effort progress through independent resources.

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 ShutdownCoordinator

fn default() -> ShutdownCoordinator

Returns the “default value” for a type.
