Struct AdaptiveSelector 

pub struct AdaptiveSelector {
    pub ratio_threshold: f64,
    pub sample_size: usize,
}

Adaptive compression selector.

Samples the first N bytes of input, compresses with each available compressor, and picks the one with the best ratio (if it meets the threshold). Falls back to NoCompression if nothing helps.

Fields

ratio_threshold: f64

Minimum compression ratio (compressed/original) to justify compression. E.g., 0.9 means compression must achieve at least 10% reduction.

sample_size: usize

Maximum sample size (bytes) for the trial compression.

Implementations

impl AdaptiveSelector

pub fn select( &self, data: &[u8], registry: &CompressorRegistry, ) -> CompressionType

Given a payload, select the best compressor from the registry. Returns the compression type to use.

Trait Implementations

impl Default for AdaptiveSelector

fn default() -> Self

Returns the “default value” for a type.
