Struct PromptCompressor 

pub struct PromptCompressor {
    pub max_tokens: usize,
    pub compression_ratio: f64,
}

Applies lossless and near-lossless text compression to reduce token count.

Fields

max_tokens: usize

Maximum tokens the compressed output should occupy (soft limit).

compression_ratio: f64

Target compression ratio (0.0–1.0). 0.8 means aim to keep 80% of chars.

Implementations

impl PromptCompressor

pub fn new(max_tokens: usize, compression_ratio: f64) -> Self

Create a compressor with the given limits.

pub fn compress(&self, text: &str) -> String

Compress text by:

1. Collapsing redundant whitespace.
2. Deduplicating consecutive identical sentences.
3. Dropping common filler phrases.
4. Abbreviating frequent verbose patterns.

pub fn estimate_savings(&self, original: &str, compressed: &str) -> f64

Fraction of characters saved: (orig - compressed) / orig.
