Enum Compression 

pub enum Compression {
    None,
    Zlib,
    Bzp2,
    Lz4,
}

A compression method understood by this library.

Variants

None

No compression; the header’s compression field is all zeros.

Zlib

zlib, as defined by the standard.

Bzp2

bzip2, as defined by the standard.

Lz4

LZ4, a de-facto extension shared with Python asdf.

Implementations

impl Compression

pub fn from_name(name: &str) -> Result<Self>

Parse the four-byte identifier.

An empty name means no compression, matching the all-zero field.

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

The identifier as written to the block header.

pub fn is_available(self) -> bool

Whether support for this method was compiled in.

pub fn decompress(self, data: &[u8], expected_size: usize) -> Result<Vec<u8>>

Decompress data, which is expected to expand to expected_size bytes.

pub fn compress(self, data: &[u8]) -> Result<Vec<u8>>

Compress data.
