Struct CompressionConfig 

pub struct CompressionConfig {
    pub compression_type: CompressionType,
    pub threshold: usize,
}

Compression configuration for the storage engine

Fields

compression_type: CompressionType

The compression algorithm to use

threshold: usize

Minimum page data size to compress (smaller pages are stored uncompressed) Default: 512 bytes

Implementations

impl CompressionConfig

pub fn none() -> Self

Create a new compression config with no compression

pub fn lz4() -> Self

Create a compression config with LZ4 (fast compression)

pub fn zstd() -> Self

Create a compression config with ZSTD at default level

pub fn zstd_level(level: i32) -> Self

Create a compression config with ZSTD at specified level

pub fn with_threshold(self, threshold: usize) -> Self

Set the compression threshold

pub fn is_enabled(&self) -> bool

Check if compression is enabled

pub fn validate(&self) -> Result<(), ConfigError>

Validate the compression configuration

Validation Rules

• threshold: must be between 64 bytes and 64KB
• ZSTD level: must be between 1 and 22

Errors

Returns ConfigError if validation fails
