Enum CompactionOutcome 

pub enum CompactionOutcome {
    Compacted,
    ProbeRejected,
    NoChange,
}

Return type from compact_context() that distinguishes between successful compaction, probe rejection, and no-op.

Gives maybe_compact() enough information to handle probe rejection without triggering the Exhausted state — which would only be correct if summarization itself is stuck.

Variants

Compacted

Messages were drained and replaced with a summary.

ProbeRejected

Probe rejected the summary — original messages are preserved. Caller must NOT check freed_tokens or transition to Exhausted.

NoChange

No compaction was performed (too few messages, empty to_compact, etc.).

Trait Implementations

impl Clone for CompactionOutcome

fn clone(&self) -> CompactionOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompactionOutcome

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

Formats the value using the given formatter.

impl PartialEq for CompactionOutcome

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