Struct ChunkedEvent 

Source 
pub struct ChunkedEvent<P, E, N = Ethereum> { /* private fields */ }
Expand description

A chunked event query builder.

Created via Event::chunked. Configure chunk size and concurrency, then call query or query_raw.

Attempts the full block range optimistically first. If that fails, the range is split into chunk_size-block windows queried concurrently (bounded by max_concurrent). If an individual chunk still fails, each block in that chunk is queried individually.

Implementations§

Source§

impl<P, E, N> ChunkedEvent<P, E, N>

Source

pub fn chunk_size(self, chunk_size: u64) -> Self

Sets the chunk size in blocks (default: 1 000).

§Panics

Panics if chunk_size is 0.

Source

pub fn concurrent(self, max_concurrent: usize) -> Self

Sets the maximum number of concurrent chunk requests (default: 5).

§Panics

Panics if max_concurrent is 0.

Source§

impl<P: Provider<N> + Clone, E: SolEvent, N: Network> ChunkedEvent<P, E, N>

Source

pub async fn query(&self) -> Result<Vec<(E, Log)>, Error>

Queries the blockchain for matching event logs, decoding them.

See query_raw for the full description of the chunked strategy.

Source

pub async fn query_raw(&self) -> TransportResult<Vec<Log>>

Queries the blockchain for matching event logs, without decoding.

Attempts the full block range optimistically first. If that fails, splits the range into chunk_size-block windows queried concurrently (up to max_concurrent at a time). If an individual chunk still fails, falls back to querying each block individually.
