An ABCI application.

Provided Methods

fn echo(&self, request: RequestEcho) -> Result<ResponseEcho, ResponseException>

Echo back the same message as provided in the request.

fn flush( &self, _request: RequestFlush, ) -> Result<ResponseFlush, ResponseException>

Signals that messages queued on the client should be flushed to the server.

fn info(&self, request: RequestInfo) -> Result<ResponseInfo, ResponseException>

Provide information about the ABCI application.

fn init_chain( &self, _request: RequestInitChain, ) -> Result<ResponseInitChain, ResponseException>

Called once upon genesis.

fn query( &self, _request: RequestQuery, ) -> Result<ResponseQuery, ResponseException>

Query the application for data at the current or past height.

fn check_tx( &self, _request: RequestCheckTx, ) -> Result<ResponseCheckTx, ResponseException>

Check the given transaction before putting it into the local mempool.

fn list_snapshots( &self, _request: RequestListSnapshots, ) -> Result<ResponseListSnapshots, ResponseException>

Used during state sync to discover available snapshots on peers.

fn offer_snapshot( &self, _request: RequestOfferSnapshot, ) -> Result<ResponseOfferSnapshot, ResponseException>

Called when bootstrapping the node using state sync.

fn load_snapshot_chunk( &self, _request: RequestLoadSnapshotChunk, ) -> Result<ResponseLoadSnapshotChunk, ResponseException>

Used during state sync to retrieve chunks of snapshots from peers.

fn apply_snapshot_chunk( &self, _request: RequestApplySnapshotChunk, ) -> Result<ResponseApplySnapshotChunk, ResponseException>

Apply the given snapshot chunk to the application’s state.

fn extend_vote( &self, _request: RequestExtendVote, ) -> Result<ResponseExtendVote, ResponseException>
