Expand description

A builder, used to prepare and instantiate a new TestNode.

Fields§

§app_state: Option<Bytes>§keyring: BTreeMap<VerificationKey, SigningKey>§on_block: Option<OnBlockFn>§ts_callback: Option<TsCallbackFn>§initial_timestamp: Option<Time>§chain_id: Option<String>§hardcoded_genesis: Option<Genesis>

Hardcodes a genesis to be used for the chain. Useful if you’re trying to test cometbft compatibility but should not be used typically.

§keys: Vec<(SigningKey, VerificationKey)>

Specifies hardcoded keys to be assigned to validators. Lowest indices are assigned first. If not enough are provided, random keys will be generated for the remaining validators. The default behavior is to generate random keys if none are supplied.

Implementations§

Source§

impl Builder

Source

pub async fn init_chain<C>(self, consensus: C) -> Result<TestNode<C>, Error>
where C: Service<ConsensusRequest, Response = ConsensusResponse, Error = BoxError> + Send + Clone + 'static, C::Future: Send + 'static, C::Error: Sized,

Consumes this builder, using the provided consensus service.

This function returns an error if the builder was not fully initialized, or if the application could not successfully perform the chain initialization.

See TestNode for more information on the consensus service.

Source§

impl Builder

Source

pub fn app_state(self, app_state: impl Into<Bytes>) -> Self

Sets the app_state_bytes to send the ABCI application upon chain initialization.

Source

pub fn single_validator(self) -> Self

Generates a single set of validator keys.

Source

pub fn two_validators(self) -> Self

Generates a pair of validator keys.

Source

pub fn on_block<F>(self, f: F) -> Self
where F: FnMut(Block) + Send + Sync + 'static,

Sets a callback that will be invoked when a new block is constructed.

Source

pub fn ts_callback<F>(self, f: F) -> Self
where F: Fn(Time) -> Time + Send + Sync + 'static,

Sets a callback that will be invoked when a block is committed, to increment the timestamp.

Source

pub fn with_initial_timestamp(self, initial_time: Time) -> Self

Sets the starting time for the test node. If not called, the current timestamp will be used.

Source

pub fn with_keys(self, keys: Vec<(SigningKey, VerificationKey)>) -> Self

Sets the keys used by validators.

Source

pub fn with_tendermint_genesis(self, genesis: Genesis) -> Self

Add the provided Tendermint [Genesis] to the builder.

This will override other configurations and hardcode the genesis data.
