Struct StoredBlockBodyIndices

Source
pub struct StoredBlockBodyIndices {
    pub first_tx_num: TxNumber,
    pub tx_count: NumTransactions,
}
Expand description

The storage of the block body indices.

It has the pointer to the transaction Number of the first transaction in the block and the total number of transactions.

Fields§

§first_tx_num: TxNumber

The number of the first transaction in this block

Note: If the block is empty, this is the number of the first transaction in the next non-empty block.

§tx_count: NumTransactions

The total number of transactions in the block

NOTE: Number of transitions is equal to number of transactions with additional transition for block change if block has block reward or withdrawal.

Implementations§
