Enum SendCompletion 

pub enum SendCompletion {
    WhenSettled,
    WhenCreated,
}

When a SendMessage call should return.

The A2A default is the waiting one, which is easy to get backwards: SendMessageConfiguration.return_immediately is a proto3 bool and so defaults to false, and false obliges the server to wait until the task settles before returning (spec/a2a.proto:155). A conformant client that sends no configuration at all — which is what the official SDKs do — is therefore promised a settled task, not an acknowledgement.

Modelled as an enum rather than the wire’s bare bool because send_message(…, false) at a call site reads as “don’t” with no way to tell what is being declined, and the polarity is already the trap here.

Lives in the domain because both directions need it: the server decodes it from the request, and the client Transport port sets it on the way out.

Variants

WhenSettled

Wait until the task reaches a terminal or interrupted state. The spec default, and what a client that sent no configuration is owed.

WhenCreated

Return as soon as the message is accepted, even if the agent is still working (return_immediately = true).

What a caller doing its own follow-up wants: it keeps its deadline in charge instead of inheriting the server’s.

Implementations

impl SendCompletion

pub fn return_immediately(self) -> bool

The wire spelling. Note the inversion — this is why the enum exists.
