Compression capability (intentionally abstracted from router process).

Required Methods

fn ncd_sym(&self, left: &[u8], right: &[u8]) -> Result<f64, CompressionError>

Symmetric NCD-like distance.

fn compression_distance( &self, left: &[u8], right: &[u8], ) -> Result<f64, CompressionError>

CMR Section 3.2 compression distance from spec: C(XY)-C(X) + C(YX)-C(Y).

fn intrinsic_dependence( &self, data: &[u8], max_order: i64, ) -> Result<f64, CompressionError>

Intrinsic dependence.

Provided Methods

fn batch_compression_distance( &self, target: &[u8], candidates: &[Vec<u8>], ) -> Result<Vec<f64>, CompressionError>

Batch CMR distance, defaulting to repeated scalar calls.

fn batch_ncd_sym( &self, target: &[u8], candidates: &[Vec<u8>], ) -> Result<Vec<f64>, CompressionError>

Batch NCD, defaulting to repeated scalar calls.
