Struct StreamPreamble 

pub struct StreamPreamble {
    pub kind: i32,
    pub request_id: String,
    pub authorized: bool,
    pub route: String,
    pub timeout_ms: u32,
    pub client_addr: String,
    pub scheme: String,
}

the first thing on every exchange stream, node -> worker. It carries only what the worker cannot derive from the HTTP bytes that follow and what it must not infer from client-supplied headers - identity above all.

Fields

kind: i32

what the bytes after this preamble are. A field rather than a framing tag, so a new stream semantic costs no new mechanism.

request_id: String

authorized: bool

the caller holds agent-endpoint call permission for this agent and deployment. Always true on a non-public route.

route: String

the manifest template that matched, e.g. “/items/{id}”

timeout_ms: u32

relative, because node and worker clocks are not synchronized. 0 imposes no deadline.

client_addr: String

end client address, host only

scheme: String

“http” or “https” as the end client saw it; not derivable worker-side

NEXT_ID: 8

Implementations

impl StreamPreamble

pub fn kind(&self) -> AgentEndpointKind

Returns the enum value of kind, or the default if the field is set to an invalid enum value.

pub fn set_kind(&mut self, value: AgentEndpointKind)
