Struct SetClientConfig 

pub struct SetClientConfig {
    pub attrs: Attrs,
    pub rank: Rank,
    pub reply: PortRef<StatusOverlay>,
}

Push client configuration overrides to this host agent’s process.

The attrs are installed as Source::ClientOverride (lowest explicit priority), so the host’s own env vars and file config take precedence. This message is idempotent — sending the same attrs twice replaces the layer wholesale.

Request-reply: the reply acts as a barrier confirming the config is installed. The fatal-on-failure / best-effort policy is the caller’s contract, not this message’s; for the canonical attach-time contract see the HM-* invariants in host_mesh.rs.

Fields

attrs: Attrs

rank: Rank

This host’s ordinal within the config-push cast region, stamped by the cast layer. Used to position this host’s install ack overlay.

reply: PortRef<StatusOverlay>

Streaming install ack. Each host posts a single-rank overlay at its ordinal once it has installed the config; the caller reduces these into a StatusMesh barrier and can name exactly which hosts (if any) never acknowledged (HM-4). StatusMesh is used here only as a per-rank presence/ack barrier — the status value itself is not meaningful (see the handler).

Trait Implementations

Performs copy-assignment from source.

impl Debug for SetClientConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SetClientConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Handler<SetClientConfig> for HostAgent

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

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 SetClientConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
