Trait XmtpMlsBidiStreams 

pub trait XmtpMlsBidiStreams: MaybeSend + MaybeSync {
    type SubscribeStream: Stream<Item = Result<SubscribeResponse, Self::Error>> + MaybeSend;
    type Error: RetryableError + 'static;

    // Required method
    fn subscribe_bidi<'life0, 'async_trait>(
        &'life0 self,
        requests: BoxStream<'static, SubscribeRequest>,
    ) -> Pin<Box<dyn Future<Output = Result<Self::SubscribeStream, Self::Error>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

The XIP-83 bidirectional subscription: one long-lived stream carrying group and welcome messages, mutated in place (no reconnect on membership change) and kept alive with WebSocket-style ping/pong. Native-only — gRPC-Web transports cannot speak full-duplex, so browsers stay on XmtpMlsStreams with a client-side watchdog.

Required Associated Types

type SubscribeStream: Stream<Item = Result<SubscribeResponse, Self::Error>> + MaybeSend

type Error: RetryableError + 'static

Required Methods

fn subscribe_bidi<'life0, 'async_trait>( &'life0 self, requests: BoxStream<'static, SubscribeRequest>, ) -> Pin<Box<dyn Future<Output = Result<Self::SubscribeStream, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Open the bidirectional stream. requests is the outbound client→server frame stream (typically fed by a channel; the first frame is usually a Mutate naming the initial topic set); the returned stream yields the server→client frames.
