Struct Offer 

pub struct Offer {
    pub realm: [u8; 32],
    pub procedure: String,
    pub handler: Option<Handler>,
    pub stream: Option<StreamOffer>,
    pub realm_key: Option<Vec<u8>>,
    pub confidential: Confidentiality,
    pub keyed_since_ms: Option<i64>,
    pub policy: Option<Policy>,
}

A procedure to serve: its realm and name, exactly one of a unary handler and a stream offer, and, for an org procedure, the realm key the org directory must be signed with, as the realm’s members pin it; a procedure in this node’s own namespace needs none.

Fields

realm: [u8; 32]

procedure: String

handler: Option<Handler>

stream: Option<StreamOffer>

realm_key: Option<Vec<u8>>

confidential: Confidentiality

How the procedure takes its requests: whether its advertisement names this node’s KEM key, with kem_advertise on, and whether it takes clear ones.

keyed_since_ms: Option<i64>

When the procedure was first advertised naming the key (unix ms), from which its keyless window runs; serving sets it to now when None. A pool keeps it across the links it serves on, so no link reopens the window.

policy: Option<Policy>

What the procedure requires of a request’s UCAN: None serves any caller (an open procedure ignores any token), and a Policy serves only a request whose token it authorizes (authorize.rs).

Implementations

impl Offer

pub fn unary(realm: [u8; 32], procedure: &str, handler: Handler) -> Offer

A unary procedure, with no realm key.

pub fn stream( realm: [u8; 32], procedure: &str, mode: StreamMode, handler: StreamHandler, ) -> Offer

A streaming procedure of mode, with no realm key.

Trait Implementations

impl Clone for Offer

fn clone(&self) -> Self

Returns a duplicate of the value.

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