}

JSON-level message body transported inside a WSCALL frame.

The wire format uses short single-letter keys and a numeric k tag to minimize per-frame overhead:

Variant	k	Fields
ApiRequest	0	i r p a m
EventEmit	1	i n d a m e
ApiResponse	2	i o s d m [er]
EventAck	3	i o rc [er]

Variants

ApiRequest

Client-to-server API request.

Fields

request_id: u64

route: String

params: Value

attachments: Vec<FileAttachment>

metadata: Value

ApiResponse

Server-to-client API response.

Fields

request_id: u64

ok: bool

status: u16

data: Value

error: Option<ErrorPayload>

metadata: Value

EventEmit

event_id: u64

name: String

data: Map<String, Value>

attachments: Vec<FileAttachment>

metadata: Value

expect_ack: bool

EventAck

Acknowledgement for an emitted event.

Fields

event_id: u64

ok: bool

receipt: Value

error: Option<ErrorPayload>
