Expand description

ZIP compression method, mirroring zip-rs CompressionMethod for the common methods plus an Unknown(raw) that preserves the offending value.

Variants§

Stored

Method 0 — no compression (raw passthrough / in-place window).

Deflated

Method 8 — classic DEFLATE.

Deflate64

Method 9 — Deflate64 / “enhanced deflate”.

Bzip2

Method 12 — bzip2.

Lzma

Method 14 — LZMA (with the 4-byte ZIP wrapper prefix).

Zstd

Method 93 — Zstandard.

Xz

Method 95 — XZ.

Shrunk

Method 1 — legacy Shrink (not decoded; recognized so it can be named).

Reduced

Methods 2–5 — legacy Reduce (not decoded).

Imploded

Method 6 — legacy Implode (not decoded).

DclImploded

Method 10 — PKWARE DCL Implode (not decoded).

IbmCmpsc

Method 16 — IBM z/OS CMPSC (not decoded).

IbmTerse

Method 18 — IBM TERSE (not decoded).

IbmLz77

Method 19 — IBM LZ77 / PFS (not decoded).

Mp3

Method 94 — MP3 (not decoded).

Jpeg

Method 96 — JPEG variant (not decoded).

WavPack

Method 97 — WavPack (not decoded).

Ppmd

Method 98 — PPMd (not decoded).

Unknown(u16)

Any other method id — value preserved so callers can report it.

Trait Implementations§

impl Clone for CompressionMethod

fn clone(&self) -> CompressionMethod

Returns a duplicate of the value. Read more

1.0.0 (const: unstable) · Source§

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

Performs copy-assignment from source. Read more

impl Copy for CompressionMethod

impl Debug for CompressionMethod

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

Formats the value using the given formatter. Read more

impl Eq for CompressionMethod

impl PartialEq for CompressionMethod

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

Tests for self and other values to be equal, and is used by ==.

1.0.0 (const: unstable) · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
