Struct SpawnProcs 

pub struct SpawnProcs {
    pub rank: Rank,
    pub proc_mesh_id: ProcMeshId,
    pub num_per_host: usize,
    pub client_config_override: Attrs,
    pub host_mesh_id: Option<HostMeshId>,
    pub default_bootstrap_command: Option<BootstrapCommand>,
    pub proc_bind: Option<Vec<ProcBind>>,
    pub bootstrap_commands: Option<Vec<Option<BootstrapCommand>>>,
    pub status_reply: Option<PortRef<StatusOverlay>>,
}

Cast to every HostAgent to spawn a mesh’s per-host proc slots in one message. Identity is positional: each recipient derives its procs’ ids/ranks from its stamped rank plus proc_mesh_id/num_per_host, since a shared cast payload can’t carry a per-host id (unlike CreateOrUpdate).

Fields

rank: Rank

This host’s ordinal within the cast region, stamped by the cast layer.

proc_mesh_id: ProcMeshId

Proc mesh id used to deterministically derive per-host proc ids.

num_per_host: usize

Number of procs to spawn on this host.

client_config_override: Attrs

Config values to set on each spawned proc’s global config, at the ClientOverride layer.

host_mesh_id: Option<HostMeshId>

The HostMesh that owns these procs (used by DrainHost for selective drain).

default_bootstrap_command: Option<BootstrapCommand>

Bootstrap command to use when no per-rank override applies.

proc_bind: Option<Vec<ProcBind>>

Optional per-proc CPU/NUMA binding, indexed by per-host slot. HostMesh::spawn already rejects a length that doesn’t match the per-host extent, so the handler is deliberately tolerant of a missing slot (including an index past the vec’s length): it spawns with no binding rather than panicking.

bootstrap_commands: Option<Vec<Option<BootstrapCommand>>>

Optional per-rank bootstrap overrides, indexed by absolute proc rank (num_per_host * host_rank + per_host_rank).

status_reply: Option<PortRef<StatusOverlay>>

Spawn ack: the host posts one multi-rank overlay covering all of its procs; the caller reduces these per-host overlays into a StatusMesh barrier.

Trait Implementations

impl Clone for SpawnProcs

fn clone(&self) -> SpawnProcs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpawnProcs

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SpawnProcs

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Handler<SpawnProcs> for HostAgent

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Context<'_, Self>, spawn: SpawnProcs, ) -> 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 SpawnProcs

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

A globally unique numeric identifier for this type.

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 SpawnProcs

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
