Enum PruningStrategy 

pub enum PruningStrategy {
    Reactive,
    TaskAware,
    Mig,
    Subgoal,
    SubgoalMig,
}

Pruning strategy for tool-output eviction inside the compaction pipeline (#1851, #2022).

When context-compression feature is enabled, this replaces the default oldest-first heuristic with scored eviction.

Variants

Reactive

Oldest-first eviction — current default behavior.

TaskAware

Short LLM call extracts a task goal; blocks are scored by keyword overlap and pruned lowest-first. Requires context-compression feature.

Mig

Coarse-to-fine MIG scoring: relevance − redundancy with temporal partitioning. Requires context-compression feature.

Subgoal

Subgoal-aware pruning: tracks the agent’s current subgoal via fire-and-forget LLM extraction and partitions tool outputs into Active/Completed/Outdated tiers (#2022). Requires context-compression feature.

SubgoalMig

Subgoal-aware pruning combined with MIG redundancy scoring (#2022). Requires context-compression feature.

Implementations

impl PruningStrategy

pub fn is_subgoal(self) -> bool

Returns true when the strategy is subgoal-aware (Subgoal or SubgoalMig).

Trait Implementations

impl Clone for PruningStrategy

fn clone(&self) -> PruningStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PruningStrategy

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

Formats the value using the given formatter.

impl Default for PruningStrategy

fn default() -> PruningStrategy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PruningStrategy

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl FromStr for PruningStrategy

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for PruningStrategy

fn eq(&self, other: &PruningStrategy) -> 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 PruningStrategy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PruningStrategy

impl Eq for PruningStrategy
