Struct PromptCompressionOptimizer 

pub struct PromptCompressionOptimizer {
    pub compressor: PromptCompressor,
    pub few_shot: FewShotSelector,
    pub cot: ChainOfThoughtInjector,
    pub goal: CompressionGoal,
}

Unified facade that combines compression, few-shot selection, and CoT injection into a single optimisation pipeline.

Fields

compressor: PromptCompressor

Text compressor.

few_shot: FewShotSelector

Few-shot example selector.

cot: ChainOfThoughtInjector

Chain-of-thought injector.

goal: CompressionGoal

High-level optimisation objective.

Implementations

impl PromptCompressionOptimizer

pub fn new(goal: CompressionGoal) -> Self

Create an optimizer with sensible defaults.

pub fn optimize(&self, prompt: &str, token_budget: usize) -> String

Optimise a single prompt within the given token_budget.

• Always applies compression.
• Injects few-shot examples if the budget allows.
• Adds CoT scaffolding when the goal is MaximizeClarity or BalancedCostQuality.

pub fn optimize_batch( &self, prompts: &[String], token_budget: usize, ) -> Vec<String>

Optimise a batch of prompts, each within the same token_budget.
