Struct BlockUndoLog 

pub struct BlockUndoLog {
    pub entries: Vec<UndoEntry>,
}

Undo log for a single block

Contains all UTXO changes made by a block, allowing perfect reversal of the block’s effects on the UTXO set.

Entries are stored in reverse order (most recent first) to allow efficient undo by iterating forward.

Fields

entries: Vec<UndoEntry>

Entries in reverse order (most recent first) This allows efficient undo: iterate forward and restore previous_utxo, remove new_utxo

impl BlockUndoLog

pub fn new() -> Self

Add an undo entry to the log

pub fn is_empty(&self) -> bool

Check if the undo log is empty
