Struct ThresholdCompactor 

pub struct ThresholdCompactor { /* private fields */ }

Compacts when context usage exceeds a threshold. It identifies turns to keep (most recent N) and applies the configured compaction strategy to older tool results.

Implementations

impl ThresholdCompactor

pub fn new( threshold: f64, keep_recent_turns: usize, tool_compaction: ToolCompaction, ) -> Result<Self, CompactorConfigError>

Creates a new threshold compactor.

Arguments

• threshold - Context utilization ratio (0.0-1.0, exclusive)
• keep_recent_turns - Number of recent turns to preserve
• tool_compaction - Strategy for handling old tool results

Returns

Error if parameters are invalid.

Trait Implementations

impl Compactor for ThresholdCompactor

fn should_compact(&self, context_used: i64, context_limit: i32) -> bool

Returns true if compaction should occur before this LLM call.

fn compact( &self, conversation: &mut Vec<Message>, compact_summaries: &HashMap<String, String>, ) -> CompactionResult

Performs synchronous compaction on the conversation. Returns the compaction statistics.

fn is_async(&self) -> bool

Returns true if this compactor requires async compaction. When true, the caller should use AsyncCompactor::compact_async() instead of compact().
