Struct TxData

Source 
pub struct TxData<DL> {
    pub rtx: Arc<ResolvedTransaction>,
    pub data_loader: DL,
    pub program: Bytes,
    pub script_group: Arc<ScriptGroup>,
}
Expand description

Context data for current running transaction & script

Fields§

§rtx: Arc<ResolvedTransaction>

ResolvedTransaction.

§data_loader: DL

Data loader.

§program: Bytes

Ideally one might not want to keep program here, since program is totally deducible from rtx + data_loader, however, for a demo here, program does help us save some extra coding.

§script_group: Arc<ScriptGroup>

The script group to which the current program belongs.
