Struct InMemoryJournal 

pub struct InMemoryJournal { /* private fields */ }

Dev-only in-memory chain-signed journal.

Implementations

impl InMemoryJournal

pub fn new() -> Self

Empty journal.

pub fn entries(&self) -> &[JournalEntry]

Borrow the full entry list — read-only view for transparency-log publishers.

Trait Implementations

impl Debug for InMemoryJournal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InMemoryJournal

fn default() -> InMemoryJournal

Returns the “default value” for a type.

impl PersistentJournal for InMemoryJournal

fn append( &mut self, token: ConsumedToken, signer: &dyn JournalSigner, ) -> Result<JournalEntry, JournalError>

Append a consumed token. Duplicate token_hash is rejected with JournalError::DuplicateToken. Success returns the newly-created entry so the caller can verify / publish it.

fn verify_chain(&self) -> Result<(), JournalError>

Full chain integrity + signature verification. Returns Ok(()) if every entry’s entry_hash matches its re-computation and every signature validates under signer_pubkey; otherwise surfaces the first failing index.

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

Last entry’s entry_hash, or GENESIS_PREV_HASH for an empty journal. Useful for external publishing (transparency log).

fn len(&self) -> usize

Count entries.

fn is_duplicate(&self, token_hash: &[u8; 32]) -> bool

Duplicate check — O(n) linear scan on in-memory, backend-specific on WAL-backed.

fn is_empty(&self) -> bool

Empty journal check.
