Enum CheckpointCompression 

#[repr(i32)]
pub enum CheckpointCompression {
    None = 0,
    Zstd = 1,
    Lz4 = 2,
}

Compression algorithm for hummock version checkpoint serialization.

Variants

None = 0

No compression.

NOTE: The numeric values are aligned with protobuf CheckpointCompressionAlgorithm.

Zstd = 1

Zstd compression (default, good balance between ratio and speed).

Lz4 = 2

Lz4 compression (faster but lower ratio).

Trait Implementations

impl Clone for CheckpointCompression

fn clone(&self) -> CheckpointCompression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckpointCompression

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

Formats the value using the given formatter.

impl Default for CheckpointCompression

fn default() -> CheckpointCompression

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CheckpointCompression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CheckpointCompression

fn eq(&self, other: &CheckpointCompression) -> 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 CheckpointCompression

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for CheckpointCompression

impl Eq for CheckpointCompression

impl StructuralPartialEq for CheckpointCompression
