Struct ckb_sdk::traits::default_impls::DefaultCellCollector

pub struct DefaultCellCollector { /* private fields */ }

A cell collector use ckb-indexer as backend

Implementations

impl DefaultCellCollector

pub fn new(ckb_client: &str) -> DefaultCellCollector

pub fn acceptable_indexer_leftbehind(&self) -> u64

THe acceptable ckb-indexer leftbehind block number (default = 1)

pub fn set_acceptable_indexer_leftbehind(&mut self, value: u64)

Set the acceptable ckb-indexer leftbehind block number

pub fn check_ckb_chain(&mut self) -> Result<(), CellCollectorError>

Check if ckb-indexer synced with ckb node. This will check every 50ms for 100 times (more than 5s in total, since ckb-indexer’s poll interval is 2.0s).

Trait Implementations

impl CellCollector for DefaultCellCollector

fn collect_live_cells(
    &mut self,
    query: &CellQueryOptions,
    apply_changes: bool
) -> Result<(Vec<LiveCell>, u64), CellCollectorError>

Collect live cells by query options, if apply_changes is true will mark all collected cells as dead cells.

fn lock_cell(&mut self, out_point: OutPoint) -> Result<(), CellCollectorError>

Mark this cell as dead cell

fn apply_tx(&mut self, tx: Transaction) -> Result<(), CellCollectorError>

Mark all inputs as dead cells and outputs as live cells in the transaction.

fn reset(&mut self)

Clear cache and locked cells
