Struct RuleBasedCompressor 

pub struct RuleBasedCompressor { /* private fields */ }

Scores messages by importance and removes lowest-scored first.

Scoring table (configurable):

• System messages: never removed (score ∞)
• Last recent_count messages: 0.9
• Tool-result messages: 0.7
• Older user/assistant messages: 0.3

Example

use traitclaw_core::context_managers::RuleBasedCompressor;

let compressor = RuleBasedCompressor::new(0.85, 3);

Implementations

impl RuleBasedCompressor

pub fn new(threshold: f64, recent_count: usize) -> Self

Create a compressor with custom threshold and recent-message protection.

• threshold: 0.0–1.0, fraction of context_window triggering compression.
• recent_count: number of most-recent messages to protect from removal.

Trait Implementations

impl ContextManager for RuleBasedCompressor

fn prepare<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, messages: &'life1 mut Vec<Message>, context_window: usize, state: &'life2 mut AgentState, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Prepare the message list by pruning or compressing if necessary.

fn estimate_tokens(&self, messages: &[Message]) -> usize

Estimate the total token count for a message list.

impl Default for RuleBasedCompressor

fn default() -> Self

Returns the “default value” for a type.
