Struct StoredBlockBodyIndices
pub struct StoredBlockBodyIndices {
pub first_tx_num: u64,
pub tx_count: u64,
}
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: u64
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: u64
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§
§impl StoredBlockBodyIndices
impl StoredBlockBodyIndices
pub const fn bitflag_encoded_bytes() -> usize
pub const fn bitflag_encoded_bytes() -> usize
Used bytes by [StoredBlockBodyIndicesFlags
]
pub const fn bitflag_unused_bits() -> usize
pub const fn bitflag_unused_bits() -> usize
Unused bits for new fields by [StoredBlockBodyIndicesFlags
]
§impl StoredBlockBodyIndices
impl StoredBlockBodyIndices
pub const fn tx_num_range(&self) -> Range<u64>
pub const fn tx_num_range(&self) -> Range<u64>
Return the range of transaction ids for this block.
pub const fn last_tx_num(&self) -> u64
pub const fn last_tx_num(&self) -> u64
Return the index of last transaction in this block unless the block is empty in which case it refers to the last transaction in a previous non-empty block
pub const fn first_tx_num(&self) -> u64
pub const fn first_tx_num(&self) -> u64
First transaction index.
Caution: If the block is empty, this is the number of the first transaction in the next non-empty block.
pub const fn next_tx_num(&self) -> u64
pub const fn next_tx_num(&self) -> u64
Return the index of the next transaction after this block.
