Struct DrainHost 

pub struct DrainHost {
    pub timeout: Duration,
    pub max_in_flight: usize,
    pub host_mesh_name: Option<Name>,
    pub ack: PortRef<()>,
}

Drain user procs on this host but keep the host, service proc, and networking alive. Used during mesh stop/shutdown so that forwarder flushes can still reach remote hosts.

If host_mesh_name is Some, only procs belonging to that mesh are stopped (selective drain). If None, all procs are terminated (full drain).

Fields

timeout: Duration

max_in_flight: usize

host_mesh_name: Option<Name>

ack: PortRef<()>

Trait Implementations

impl Debug for DrainHost

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DrainHost

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Handler<DrainHost> for HostAgent

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Context<'_, Self>, msg: DrainHost, ) -> 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 Named for DrainHost

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 DrainHost

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Accepts<DrainHost> for HostAgent

impl RemoteHandles<DrainHost> for HostAgent
