Struct JournalEntry 

pub struct JournalEntry {
    pub sequence: u64,
    pub prev_hash: [u8; 32],
    pub payload: Vec<u8>,
}

A single journal entry with opaque payload.

Fields

sequence: u64

Entry sequence number (1-indexed, monotonically increasing).

prev_hash: [u8; 32]

SHA-256 hash of the previous entry (zeros for the first entry).

payload: Vec<u8>

Opaque payload bytes (engine defines the format).

Trait Implementations

impl Clone for JournalEntry

fn clone(&self) -> JournalEntry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JournalEntry

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

Formats the value using the given formatter.

impl PartialEq for JournalEntry

fn eq(&self, other: &JournalEntry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
