Enum AppendLogMode 

pub enum AppendLogMode {
    Append,
    Overwrite,
}

D269 — Persistence mode (memo:Re P1 parity). Mirrors TS AppendLogStorageOptions.mode. Append (default) reads existing bucket bytes, decodes, merges new entries, encodes, writes back — the M4.B behavior. Overwrite skips the read/merge entirely and snapshots the current batch as the bucket’s full contents. Used for callers that ship full snapshots per wave (e.g. WAL replay drivers) rather than deltas. Feeding deltas into an Overwrite tier silently truncates the log to the last batch — attach_storage rejects overwrite sinks at attachment time.

Variants

Append

Read existing bucket, merge new entries, write back. M4.B default.

Overwrite

Replace bucket contents with the current batch (no read-merge).

Trait Implementations

impl Clone for AppendLogMode

fn clone(&self) -> AppendLogMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppendLogMode

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

Formats the value using the given formatter.

impl Default for AppendLogMode

fn default() -> AppendLogMode

Returns the “default value” for a type.

impl PartialEq for AppendLogMode

fn eq(&self, other: &AppendLogMode) -> 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.

impl Copy for AppendLogMode

impl Eq for AppendLogMode
