Struct BlockContext 

Source 
pub struct BlockContext {
    pub client: Client,
    pub block_id: HashStringNumber,
    /* private fields */
}
Expand description

Fetches the block header for the provided identifier.

§Parameters

  • client: RPC client used to perform the header query.
  • block_id: Hash or number identifying the target block.

§Returns

  • Ok(AvailHeader): Header returned by the node.
  • Err(Error): The RPC call failed or the block could not be resolved.

§Side Effects

  • Performs an RPC call through the client’s chain interface.

Fields§

§client: Client

Client handle used for follow-up RPC calls.

§block_id: HashStringNumber

Hash or number identifying the target block.

Implementations§

Source§

impl BlockContext

Source

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

Creates a new block context for the provided identifier.

§Arguments
  • client - Client used to perform subsequent RPC calls.
  • block_id - Hash or number identifying the target block.
Source

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

Overrides the retry policy for follow-up RPC calls.

§Arguments
  • value - Some(true) to force retries, Some(false) to disable retries, None to inherit defaults.
Source

pub fn should_retry_on_error(&self) -> bool

Reports whether RPC calls should retry after errors.

§Returns

Returns true when retries are enabled, otherwise false.

Source

pub fn hash_number(&self) -> Result<HashNumber, Error>

Resolves the stored identifier into a HashNumber.

§Returns

Returns the resolved HashNumber or an error if conversion fails.

Source

pub fn chain(&self) -> Chain

Returns a chain helper configured with the current retry policy.

Source

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

Fetches the block header associated with this context.

§Returns

Returns the header or an error when the block cannot be resolved.

Source

pub async fn event_count(&self) -> Result<usize, Error>

Counts the events emitted by the block referenced by this context.

§Returns

Returns the number of events or an error when the RPC call fails.
