sourcefn get_cell_data(&self, out_point: &OutPoint) -> Option<Bytes>
fn get_cell_data(&self, out_point: &OutPoint) -> Option<Bytes>
Fetch cell_data from storage
sourcefn get_cell_data_hash(&self, out_point: &OutPoint) -> Option<Byte32>
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. Read more
