Enum CompressionKind 

pub enum CompressionKind {
    None = 0,
    Lz4 = 1,
    Zstd = 2,
}

Compression algorithm for record payloads.

Each record stores its compression kind so that records compressed with different algorithms can coexist in the same segment. The None variant means the payload is stored uncompressed.

Variants

None = 0

No compression (default).

Lz4 = 1

LZ4 compression (fast, moderate ratio).

Zstd = 2

Zstandard compression (slower, better ratio).

Implementations

impl CompressionKind

pub fn as_byte(self) -> u8

Returns the single-byte discriminant for serialization.

pub fn from_byte(byte: u8) -> Option<Self>

Creates a CompressionKind from its byte discriminant.

Trait Implementations

impl Clone for CompressionKind

fn clone(&self) -> CompressionKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionKind

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

Formats the value using the given formatter.

impl Default for CompressionKind

fn default() -> CompressionKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CompressionKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CompressionKind

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

Formats the value using the given formatter.

impl Hash for CompressionKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CompressionKind

fn eq(&self, other: &CompressionKind) -> 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 Serialize for CompressionKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
