Enum CodecKind 

pub enum CodecKind {
    Passthrough,
    NvcompBitcomp,
    NvcompGans,
    NvcompZstd,
    DietGpuAns,
    CpuZstd,
    NvcompGDeflate,
    CpuGzip,
}

圧縮 codec の種類 (manifest に記録、後段の decompress で codec を確定するために使う)

Variants

Passthrough

NvcompBitcomp

NvcompGans

NvcompZstd

DietGpuAns

CpuZstd

NvcompGDeflate

nvCOMP GDeflate (v0.2 #9). DEFLATE-family GPU codec; output bytes are NOT gzip-compatible at the wire level (different framing) but the algorithm-level format aligns with stock DEFLATE/zlib decoders given the right wrapper.

CpuGzip

CPU gzip via flate2 (v0.4 #26). Produces RFC 1952 gzip output that any standard gunzip-aware client can decode without knowing about S4. Pair with the Content-Encoding: gzip header to serve to a browser / curl that’s never heard of S4.

Implementations

impl CodecKind

pub fn as_str(self) -> &'static str

pub fn id(self) -> u32

安定 numeric ID。s4-codec/multipart.rs の frame header に書き込む際に使う。 ⚠️ この値は wire format の一部 — 既存値の変更禁止 (新 codec は新 ID を割当)。

pub fn from_id(id: u32) -> Option<Self>

Trait Implementations

impl Clone for CodecKind

fn clone(&self) -> CodecKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CodecKind

impl Debug for CodecKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CodecKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CodecKind

impl FromStr for CodecKind

type Err = ParseCodecKindError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for CodecKind

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 CodecKind

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
