Struct WalWriter 

pub struct WalWriter { /* private fields */ }

Append-only WAL writer. Each successful Kernel::step writes one WalRecord via the kernel’s internal append path.

Implementations

impl WalWriter

pub fn new(world_id: [u8; 32], manifest_digest: [u8; 32]) -> Self

Construct a chain-only writer (Tier 1 — no signature).

pub fn with_signature( world_id: [u8; 32], manifest_digest: [u8; 32], sig_class: SignatureClass, ) -> Self

Construct a writer that signs each record under sig_class. The verifying key is pinned in the header so post-hoc verification works against the WAL bytes alone.

pub fn header(&self) -> &WalHeader

Pinned WAL header.

pub fn records(&self) -> &[WalRecord]

All records appended so far, in append order.

pub fn chain_tip(&self) -> [u8; 32]

Most recent record’s this_chain_hash, or zero if empty.

pub fn record_count(&self) -> usize

Number of records currently buffered.
