Enum CompactionStage 

#[non_exhaustive]
pub enum CompactionStage {
    BudgetReduce,
    Snip,
    Microcompact,
    ContextCollapse,
    AutoCompact,
}

The 5 progressive compaction stages (DESIGN.md §9 — borrowed from Claude Code).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BudgetReduce

60% — trim redundant tool results, keep recent full turns.

Snip

70% — drop stale file reads, keep path + hash.

Microcompact

80% — summarise older conversation segments with a cheaper model.

ContextCollapse

90% — collapse all file reads into a single inventory + key excerpts.

AutoCompact

95% — rewrite the entire conversation in compressed form with the main model.

Implementations

impl CompactionStage

pub const ALL: [CompactionStage; 5]

Stages, in order. Higher stages imply running all lower stages first.

Trait Implementations

impl Clone for CompactionStage

fn clone(&self) -> CompactionStage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CompactionStage

impl Debug for CompactionStage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CompactionStage

fn deserialize<__D>( __deserializer: __D, ) -> Result<CompactionStage, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CompactionStage

impl Hash for CompactionStage

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CompactionStage

fn eq(&self, other: &CompactionStage) -> 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 Serialize for CompactionStage

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
