Struct CompressionStats 

pub struct CompressionStats {
    pub original_bytes: u64,
    pub compressed_bytes: u64,
    pub operations: u64,
    pub failures: u64,
}

Cumulative compression statistics.

Tracks totals across multiple compress operations so callers can monitor compression effectiveness over time.

Fields

original_bytes: u64

Total original (uncompressed) bytes seen.

compressed_bytes: u64

Total compressed bytes produced.

operations: u64

Number of successful compress/decompress operations.

failures: u64

Number of failed operations.

Implementations

impl CompressionStats

pub fn ratio(&self) -> f64

Overall compression ratio (compressed / original).

Returns 0.0 when no bytes have been recorded.

pub fn record(&mut self, original: usize, compressed: usize)

Record a successful compression operation.

pub fn record_failure(&mut self)

Record a failed compression/decompression attempt.

pub fn savings_percent(&self) -> f64

Savings percentage ((1 - ratio) * 100).
