Struct CpuZstd 

pub struct CpuZstd { /* private fields */ }

CPU zstd codec。level は 1..=22 (zstd-22 は最大圧縮率、時間は長い)。

S4 default は 3 (zstd の通常 default、速度と圧縮率のバランス)。

Implementations

impl CpuZstd

pub const DEFAULT_LEVEL: i32 = 3

pub fn new(level: i32) -> Self

Trait Implementations

impl Clone for CpuZstd

fn clone(&self) -> CpuZstd

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Codec for CpuZstd

fn kind(&self) -> CodecKind

この実装が提供する codec の種類

fn compress<'life0, 'async_trait>( &'life0 self, input: Bytes, ) -> Pin<Box<dyn Future<Output = Result<(Bytes, ChunkManifest), CodecError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

圧縮: 入力 bytes → 圧縮済 bytes + manifest

fn decompress<'life0, 'life1, 'async_trait>( &'life0 self, input: Bytes, manifest: &'life1 ChunkManifest, ) -> Pin<Box<dyn Future<Output = Result<Bytes, CodecError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

解凍: 圧縮済 bytes + manifest → 元の bytes

impl Debug for CpuZstd

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

Formats the value using the given formatter.

impl Default for CpuZstd

fn default() -> Self

Returns the “default value” for a type.
