Enum rocks::options::CompressionType

#[repr(C)]pub enum CompressionType {
    NoCompression,
    SnappyCompression,
    ZlibCompression,
    BZip2Compression,

}

DB contents are stored in a set of blocks, each of which holds a sequence of key,value pairs. Each block may be compressed before being stored in a file. The following enum describes which compression method (if any) is used to compress a block.

Variants

NoCompression

NOTE: do not change the values of existing entries, as these are part of the persistent format on disk.

SnappyCompression

ZlibCompression

BZip2Compression

LZ4Compression

LZ4HCCompression

XpressCompression

ZSTD

ZSTDNotFinalCompression

Only use kZSTDNotFinalCompression if you have to use ZSTD lib older than 0.8.0 or consider a possibility of downgrading the service or copying the database files to another service running with an older version of RocksDB that doesn't have kZSTD. Otherwise, you should use kZSTD. We will eventually remove the option from the public API.

DisableCompressionOption

kDisableCompressionOption is used to disable some compression options.

Trait Implementations

impl Clone for CompressionType

fn clone(&self) -> CompressionType

Returns a copy of the value.

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

impl Ord for CompressionType

fn cmp(&self, other: &CompressionType) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<CompressionType> for CompressionType

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<CompressionType> for CompressionType

fn partial_cmp(&self, other: &CompressionType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
