Build Status

Xerial-compatible Snappy framing support for golang.

Packages using Xerial for snappy encoding use a framing format incompatible with basically everything else in existence. This package wraps Go's built-in snappy package to support it.

Apps that use this format include Apache Kafka (see https://github.com/dpkp/kafka-python/issues/126#issuecomment-35478921 for details).

Functions

func Decode

func Decode(src []byte) ([]byte, error)

Decode decodes snappy data whether it is traditional unframed or includes the xerial framing format.

func DecodeInto

func DecodeInto(dst, src []byte) ([]byte, error)

DecodeInto decodes snappy data whether it is traditional unframed or includes the xerial framing format into the specified `dst`. It is assumed that the entirety of `dst` including all capacity is available for use by this function. If `dst` is nil *or* insufficiently large to hold the decoded `src`, new space will be allocated.

func Encode

func Encode(src []byte) []byte

Encode encodes data as snappy with no framing header.

func EncodeStream

func EncodeStream(dst, src []byte) []byte

EncodeStream *appends* to the specified 'dst' the compressed 'src' in xerial framing format. If 'dst' does not have enough capacity, then a new slice will be allocated. If 'dst' has non-zero length, then if *must* have been built using this function.
