Enum CompressionType 

pub enum CompressionType {
    None,
    Lz4,
    Zstd {
        level: i32,
    },
}

Compression algorithm type for page compression

Variants

None

No compression

Lz4

LZ4 - fast compression with moderate ratio

Zstd

ZSTD - high compression ratio with configurable level Level ranges from 1 (fastest) to 22 (best compression)

Fields

level: i32

Implementations

impl CompressionType

pub fn zstd_default() -> Self

Create ZSTD compression with default level (3)

pub fn zstd_high() -> Self

Create ZSTD compression with high ratio (level 9)

pub fn zstd_max() -> Self

Create ZSTD compression with maximum ratio (level 19)

pub fn is_enabled(&self) -> bool

Check if compression is enabled

Trait Implementations

impl Clone for CompressionType

fn clone(&self) -> CompressionType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionType

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

Formats the value using the given formatter.

impl Default for CompressionType

fn default() -> CompressionType

Returns the “default value” for a type.

impl PartialEq for CompressionType

fn eq(&self, other: &CompressionType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for CompressionType
