Struct PreparedSyncRound 

pub struct PreparedSyncRound { /* private fields */ }

Immutable request and blob bodies captured by the mutable client owner. Send this value to an I/O executor; it contains no SQLite connection.

Implementations

impl PreparedSyncRound

pub fn exchange(self, transport: &mut dyn Transport) -> CompletedSyncRound

Run network I/O without accessing client state. Download errors stay at their descriptor’s position so apply retains the same completed prefix.

This drives the same RoundOperation sequence that a non-blocking host drives itself, so both paths share every decision the client makes about uploads, segment fetches, and deadline state.

pub fn request_bytes(&self) -> Vec<u8>

The encoded round message (§1.5). Uploads listed by RoundOperation::UploadGrant precede it; a host that drives the round with exchange never needs this call.

pub fn next_operation(&mut self) -> Option<RoundOperation<'_>>

The next network operation a host must perform, or None once every operation of the current exchange is answered. Call PreparedSyncRound::submit with its result, then repeat.

After an upload operation completes, the round is complete for this exchange: call PreparedSyncRound::finish and apply it, so the owner persists the pin removal before the metadata request. The applied round’s Continue returns the prepared round for the next exchange.

pub fn submit(&mut self, reply: RoundReply) -> Result<(), TransportError>

Hand the result of the last PreparedSyncRound::next_operation back. A reply of the wrong kind fails with client.invalid_round_reply and leaves the round where it was.

pub fn finish(self) -> Option<CompletedSyncRound>

The completed round once every operation is answered, ready for SyncClient::apply_sync_round.
