Enum Compression 

pub enum Compression {
    None,
    Gzip,
    Bgzf,
}

Compression applied to a sequence file.

Variants

None

Plain, uncompressed bytes.

Gzip

One deflate stream, as gzip produces. Readable start to finish only.

Bgzf

Block-compressed gzip, as bgzip produces.

Valid gzip that any tool can decompress, but split into independent members so that a reader with a .gzi index can seek into it. Costs a percent or two of compression ratio and is what the samtools ecosystem expects, so it is the default for compressed output.

Implementations

impl Compression

pub const GZIP_MAGIC: [u8; 2]

The first two bytes of a gzip member.

pub fn from_path<P: AsRef<Path>>(path: P) -> Compression

Infer compression from a file extension.

pub fn from_magic(bytes: &[u8]) -> Compression

Infer compression from the leading bytes of a stream.
