Struct WaitRankStatus 

pub struct WaitRankStatus {
    pub id: ResourceId,
    pub min_status: Status,
    pub reply: PortRef<StatusOverlay>,
}

Like GetRankStatus, but the handler defers its reply until the resource’s status is >= min_status. This avoids the race where the caller sees Stopping before the process has actually exited.

Fields

id: ResourceId

The resource identifier.

min_status: Status

The minimum status the caller wants to observe. The handler will not reply until the resource’s status is >= this threshold.

reply: PortRef<StatusOverlay>

Sparse status updates (overlays) from a rank.

Trait Implementations

impl Bind for WaitRankStatus

fn bind(&mut self, bindings: &mut Bindings) -> Result<()>

Remove parameters from bindings, and use them to update itself.

impl Clone for WaitRankStatus

fn clone(&self) -> WaitRankStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WaitRankStatus

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WaitRankStatus

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Handler<WaitRankStatus> for HostAgent

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Context<'_, Self>, msg: WaitRankStatus, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handle the next M-typed message.

impl Handler<WaitRankStatus> for ProcAgent

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Context<'_, Self>, msg: WaitRankStatus, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handle the next M-typed message.

impl<T: Controlled> Handler<WaitRankStatus> for ResourceController<T>

where State<T::StateInner>: RemoteMessage,

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Context<'_, Self>, msg: WaitRankStatus, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Forward WaitRankStatus to the underlying agents. Each agent replies directly to the caller’s accumulator port when its resource reaches the requested status.

impl Named for WaitRankStatus

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

The globally unique port for this type. Typed ports are in the range of 1<<63..1<<64-1.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.

impl Serialize for WaitRankStatus

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Unbind for WaitRankStatus

fn unbind(&self, bindings: &mut Bindings) -> Result<()>

Extract parameters from itself and store them in bindings.
