Enum AppendLogMode 

pub enum AppendLogMode {
    Append,
    Overwrite,
}

Local mirror of graphrefly_storage::AppendLogMode (next batch 2026-05-21). graphrefly-storage already depends on graphrefly-structures (for BaseChange<T>), so we can’t forward the enum the other direction without creating a dep cycle. The two declarations are intentionally identical and pre-1.0 stable; if a third mode is ever added, both must move together (Append / Overwrite are the locked D269 vocabulary).

Variants

Append

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

Overwrite

Replace bucket contents with the current batch (no read-merge). ReactiveLog::attach_storage rejects sinks declaring this mode — delta-shipping into an overwrite sink silently truncates the log to the last batch (memo:Re P1 hazard class).

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
