Directions

• Used to export json from the test case of the contract for debugging of the ckb-debugger

pub fn gen_json<'a, DL: CellDataProvider + HeaderProvider>(
    verifier: &TransactionScriptsVerifier<'a, DL>,
    resolved_tx: &ResolvedTransaction,
    group_index: usize,
    bin_path: &str,
    json_file_name: &str,
) -> String {...}

By calling this function, you can generate transaction data for ckb-debugger

verifier

CKB VM to verify transaction inputs. Get grouping information through this function.

resolved_tx

This Library provides the essential types for CKB. Get cell information, including inputs, outputs and dependencies.

• If the dep cell is bin_path data, the data filled with 0x.

group_index

Transaction group index, the index of verifier.groups(), if it out of bounds, an exception will be thrown. and if the group script is not bin_path data, also throw an exception.

bin_path

Contract path to be executed

json_file_name

File for exporting transaction data

return value

According to the ckb-debugger command generated from these data, some of the file paths will be replaced with absolute paths.

For example

pub fn dumper(&self, bin_path: &str, dumper_name: &str) -> String {
    let consensus = TX::gen_consensus();
    let tx_env = TX::gen_tx_env();
    let verifier = TransactionScriptsVerifier::new(
        &self.resolved_tx,
        &consensus,
        &self.data_loader,
        &tx_env,
    );
    ckb_debugger_dumper::gen_json(
        &verifier,
        &self.resolved_tx,
        Option::None,
        0,
        bin_path,
        dumper_name,
        Option::None,
    )
}
