Struct NoopApplication 

pub struct NoopApplication;

No-op application stub for testing and fullnode-without-ABCI mode.

Trait Implementations

impl Application for NoopApplication

fn tracks_app_hash(&self) -> bool

NoopApplication does not maintain state, so app_hash tracking is skipped.

fn create_payload(&self, _ctx: &BlockContext<'_>) -> Vec<u8>

Create a payload for a new block proposal. Typically pulls transactions from the mempool.

fn validate_block(&self, _block: &Block, _ctx: &BlockContext<'_>) -> bool

Validate a proposed block before voting.

fn validate_tx( &self, _tx: &[u8], _ctx: Option<&TxContext>, ) -> TxValidationResult

Validate a single transaction for mempool admission.

fn execute_block( &self, _txs: &[&[u8]], _ctx: &BlockContext<'_>, ) -> Result<EndBlockResponse>

Execute an entire block in one call.

fn on_commit(&self, _block: &Block, _ctx: &BlockContext<'_>) -> Result<()>

Called when a block is committed to the chain (notification).

fn on_evidence(&self, _proof: &EquivocationProof) -> Result<()>

Called when equivocation (double-voting) is detected. The application can use this to implement slashing.

fn extend_vote( &self, _block: &Block, _ctx: &BlockContext<'_>, ) -> Option<Vec<u8>>

Generate a vote extension for the given block (ABCI++ Vote Extensions). Called before casting a Vote2 (second-phase vote). Returns None to skip extension (default behavior).

fn verify_vote_extension( &self, _extension: &[u8], _block_hash: &BlockHash, _validator: ValidatorId, ) -> bool

Verify a vote extension received from another validator. Called when processing Vote2 messages that carry extensions. Returns true if the extension is valid (default: accept all).

fn query(&self, _path: &str, _data: &[u8]) -> Result<Vec<u8>>

Query application state (returns opaque bytes).

fn list_snapshots(&self) -> Vec<SnapshotInfo>

List available state snapshots for state sync.

fn load_snapshot_chunk(&self, _height: Height, _chunk_index: u32) -> Vec<u8>

Load a chunk of a snapshot at the given height.

fn offer_snapshot(&self, _snapshot: &SnapshotInfo) -> SnapshotOfferResult

Offer a snapshot to the application for state sync.

fn apply_snapshot_chunk( &self, _chunk: Vec<u8>, _chunk_index: u32, ) -> ChunkApplyResult

Apply a snapshot chunk received during state sync.
