Struct CapabilityRequest 

pub struct CapabilityRequest {
    pub id: String,
    pub capability: String,
    pub payload: Value,
    pub timeout_ms: Option<u64>,
    pub trace_id: Option<String>,
    pub span_id: Option<String>,
    pub parent_span_id: Option<String>,
    pub trace_depth: Option<u8>,
    pub caller_app: Option<String>,
}

A service capability request dispatched to a provider app. Used for both FFI (serialized as JSON bytes) and IPC (serialized as JSON).

Fields

id: String

Request correlation ID (UUID)

capability: String

Target capability name (dot-notation, e.g., “terminal.create_session”)

payload: Value

Request payload as JSON value

timeout_ms: Option<u64>

Optional per-capability timeout in milliseconds (falls back to 30s default)

trace_id: Option<String>

Root trace ID grouping all spans in one logical invocation.

span_id: Option<String>

Span ID of the caller (used as parent_span_id in sub-invocations).

parent_span_id: Option<String>

Parent span ID for this invocation (None if root).

trace_depth: Option<u8>

Current nesting depth (0 for root, max 16).

caller_app: Option<String>

Manifest name of the app that originated this request. Populated by the dispatcher when a builtin app invokes a capability via the SDK. None when the call originates from an external transport (HTTP, WS) — in that case the request is owned by the platform itself.
