Trait JmapHandler 

pub trait JmapHandler<CallerCtx>: Send + Sync {
    // Required method
    fn call(
        &self,
        method: String,
        call_id: String,
        args: Value,
        caller: CallerCtx,
    ) -> HandlerFuture;
}

Implement this for each JMAP method handler.

CallerCtx is whatever your auth layer produces — an Identity, a session token, (), etc. The dispatcher passes it through unchanged.

/set response contract

Handlers for /set methods (RFC 8620 §5.3) that create objects MUST include an "id" field (type string) in each entry of the "created" map. The dispatcher reads this field to accumulate createdIds in the response. Entries without an "id" field are silently skipped — the dispatcher cannot retroactively error a method call that already returned success.

Required Methods

fn call( &self, method: String, call_id: String, args: Value, caller: CallerCtx, ) -> HandlerFuture

method is the registered method name for this call. A single handler instance may be registered under multiple names (e.g. both "Foo/get" and "Bar/get"); this parameter lets the handler distinguish between them.

call_id is the client-supplied identifier for this invocation (RFC 8620 §3.3). Handlers may use it for logging or correlation but need not echo it — the dispatcher echoes it in the response automatically.
