Struct WaitRankStatus 

pub struct WaitRankStatus {
    pub name: Name,
    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

name: Name

The name of the resource.

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.

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.
