Struct BlockEvents 

Source 
pub struct BlockEvents { /* private fields */ }
Expand description

View that fetches events emitted by a block, optionally filtered by extrinsic.

Implementations§

Source§

impl BlockEvents

Source

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

Creates an event view for the given block.

No RPC calls are made until BlockEvents::ext or BlockEvents::block is awaited.

Source

pub async fn ext(&self, tx_index: u32) -> Result<Option<ExtrinsicEvents>, Error>

Returns events emitted by a specific extrinsic index.

§Returns
  • Ok(Some(ExtrinsicEvents)) when events exist for the given index.
  • Ok(None) when the block contains no events at that index.
  • Err(Error) when fetching or decoding event data fails.
Source

pub async fn block( &self, opts: BlockEventsOptions, ) -> Result<Vec<BlockPhaseEvent>, Error>

Fetches events for the block using the given options.

By default encoding is enabled; callers can override this via opts.

Source

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

Controls retry behaviour for event lookups: Some(true) forces retries, Some(false) disables them, and None keeps the client’s default.

Source

pub fn should_retry_on_error(&self) -> bool

Returns true when event queries retry after RPC errors.
