Struct TierCompressor 

pub struct TierCompressor { /* private fields */ }

Symmetric compressor/decompressor for cache tier entries.

Instantiate once and reuse for many compress/decompress calls.

Implementations

impl TierCompressor

pub fn new(level: u8) -> Self

Create a new TierCompressor at the given level (0–3; values above 3 are treated as level 3).

pub fn compress(&self, input: &[u8]) -> Result<Vec<u8>, CompressorError>

Compress input and return the compressed bytes.

The compressed bytes include a header that encodes the original length; pass them directly to [decompress] to recover the original.

pub fn decompress(&self, input: &[u8]) -> Result<Vec<u8>, CompressorError>

Decompress bytes previously produced by [compress].

pub fn level(&self) -> u8

Return the compression level (0–3).

pub fn compression_ratio(&self, input: &[u8]) -> Result<f64, CompressorError>

Compress input and report the compression ratio (compressed / original).

Returns 1.0 for empty inputs.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TierCompressor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
