pub fn new(source: &'a T) -> Self

Construct new BorrowedDataLoaderWrapper

Trait Implementations

impl<'a, T: ChainStore> CellDataProvider for BorrowedDataLoaderWrapper<'a, T>

fn get_cell_data(&self, out_point: &OutPoint) -> Option<Bytes>

Fetch cell_data from storage

fn get_cell_data_hash(&self, out_point: &OutPoint) -> Option<Byte32>

Fetch cell_data_hash from storage, please note that loading a large amount of cell data and calculating hash may be a performance bottleneck, so here is a separate fn designed to facilitate caching.

fn load_cell_data(&self, cell: &CellMeta) -> Option<Bytes>

Load cell_data from memory, fallback to storage access

fn load_cell_data_hash(&self, cell: &CellMeta) -> Option<Byte32>

Load cell_data_hash from memory, fallback to storage access

fn get_epoch_ext(&self, header: &HeaderView) -> Option<EpochExt>

Get corresponding EpochExt by block header

fn get_block_hash(&self, number: BlockNumber) -> Option<Byte32>

Get block header hash by block number

fn get_block_ext(&self, block_hash: &Byte32) -> Option<BlockExt>
