Struct LogChain 

pub struct LogChain { /* private fields */ }

Log chain state

Implementations

impl LogChain

pub fn new() -> Self

Create new chain with genesis block

pub async fn append(&mut self, entry: LogEntry) -> Result<LogEntry, LogError>

Append entry to chain

pub async fn append_committed( &mut self, entry: LogEntry, ) -> Result<(), LogError>

Append an already-committed entry (WAL replay path).

pub fn verify(&self) -> bool

Verify chain integrity

pub fn get_entry(&self, entry_id: &str) -> Option<&LogEntry>

pub fn generate_proof(&self, entry_id: &str) -> Option<ChainProof>

Generate a compact inclusion proof for an entry.

The proof size is O(log n):

• one Merkle path proving target entry hash membership in the chain root
• one Merkle path proving chain head hash membership in the same root

pub fn len(&self) -> usize

Get entry count

pub fn is_empty(&self) -> bool

Check if empty

pub fn current_hash(&self) -> &str

Get current hash

Trait Implementations

impl Default for LogChain

fn default() -> Self

Returns the “default value” for a type.
