Helper bound to the chain’s best (head) block view.

Implementations§

Source§

impl Best

Source

pub fn new(client: Client) -> Self

Builds a helper focused on the best (head) block.

Source

pub fn retry_on(self, error: Option<bool>) -> Self

Lets you toggle automatic retries for the calls that follow.

Source

pub async fn block_header(&self) -> Result<AvailHeader, Error>

Returns the current best block header.

§Errors

Returns Err(Error) when the head hash cannot be fetched or the header lookup fails.

Source

pub async fn block(&self) -> Result<BlockApi, Error>

Gives you a block handle for the best block.

Source

pub async fn block_info(&self) -> Result<BlockInfo, RpcError>

Returns height and hash for the best block.

Equivalent to chain().block_info(true) but respecting this helper’s retry setting.

Source

pub async fn block_hash(&self) -> Result<H256, RpcError>

Returns the hash of the best block.

Source

pub async fn block_height(&self) -> Result<u32, RpcError>

Returns the height of the best block.

Source

pub async fn legacy_block(&self) -> Result<LegacyBlock, RpcError>

Loads the legacy block view for the best block.

§Errors

Returns Err(RpcError::ExpectedData) when the node reports no legacy block for the head.

Source

pub async fn account_nonce( &self, account_id: impl Into<AccountIdLike>, ) -> Result<u32, Error>

Returns the latest nonce for the account at the best block.

Source

pub async fn account_balance( &self, account_id: impl Into<AccountIdLike>, ) -> Result<AccountData, Error>

Returns the account balances at the best block.

Source

pub async fn account_info( &self, account_id: impl Into<AccountIdLike>, ) -> Result<AccountInfo, Error>

Returns the full account record at the best block.

§Errors

Mirrors ChainApi::account_info.

Source

pub fn should_retry_on_error(&self) -> bool

Returns true when best-block queries retry after RPC errors.
