pub struct BlockQuery { /* private fields */ }
Expand description

Block query client for retrieving and parsing block information

Implementations§

Source§

impl BlockQuery

Source

pub fn new(client: OnlineClient<PolkadotConfig>) -> Self

Create a new BlockQuery instance

Source

pub async fn get_block_by_number( &self, block_number: u64, ) -> Result<BlockInfo, Error>

Get block information by block number

This method queries the latest finalized block and traverses backwards to find the requested block number. For recent blocks, this is efficient. For historical blocks far from the current height, consider using get_block_by_hash if you have the block hash.

Source

pub async fn get_block_by_hash( &self, hash_hex: &str, ) -> Result<BlockInfo, Error>

Get block information by block hash

This is the most efficient way to query a specific block if you have its hash.

Source

pub async fn get_detailed_block( &self, block_number: u64, ) -> Result<DetailedBlockInfo, Error>

Get detailed block information including extrinsics and events
