Struct BlockApi 

pub struct BlockApi { /* private fields */ }

High-level handle bound to a specific block id (height or hash).

Implementations

impl BlockApi

pub fn new(client: Client, block_id: impl Into<HashStringNumber>) -> Self

Creates a block helper for the given height or hash.

No network calls are issued up front; the block_id is stored for later RPC queries. Use the view helpers such as BlockApi::tx or BlockApi::events to fetch concrete data.

pub fn tx(&self) -> BlockWithTx

Returns a view that focuses on decoded transactions.

The returned BlockWithTx shares this helper’s retry configuration.

pub fn ext(&self) -> BlockWithExt

Returns a view that focuses on decoded extrinsics while retaining signature metadata.

pub fn raw_ext(&self) -> BlockWithRawExt

Returns a view that keeps extrinsics as raw bytes and optional signer payload information.

pub fn events(&self) -> BlockEvents

Returns a helper for fetching events from this block.

pub fn set_retry_on_error(&mut self, value: Option<bool>)

Controls retry behaviour for follow-up RPC calls made through this block helper.

• Some(true) forces retries regardless of the client’s global setting.
• Some(false) disables retries entirely.
• None keeps the client’s default configuration.

pub async fn justification(&self) -> Result<Option<GrandpaJustification>, Error>

Fetches the GRANDPA justification for this block when available.

Returns

• Ok(Some(GrandpaJustification)) when the runtime provides a justification.
• Ok(None) when no justification exists for the requested block.
• Err(Error) if the RPC layer fails or the supplied block id cannot be resolved.

pub fn should_retry_on_error(&self) -> bool

Returns true when this block view will retry failed RPC calls.
