Implementations

impl EssentialNodeClient

pub fn new(addr: String) -> Result<Self>

Create a new client with the given address.

pub async fn list_blocks(&self, range: Range<Word>) -> Result<Vec<Block>>

List blocks in the given L2 block number range.

Blocks are only created if there are valid solutions. Blocks are created on a regular interval.

pub async fn query_state( &self, contract_ca: ContentAddress, key: Key, ) -> Result<Option<Value>>

Query state in the given contract address and key.

This is the main way the front end application will interact with state. It only really makes sense to query state where you know what the ABI of the contract is. The state that’s returned is a list of words of variable size. The keys are also variable sized lists of words. To make use of this API you need to know what type of contract you are querying.
