Functions ¶
func DecodeZstd ¶
DecodeZstd calls DecodeAll on the global zstd decoder.
See: (*zstd.Decoder).DecodeAll
Types ¶
type Compressor ¶
type Compressor interface {
// Name is the name of the compression algorithm.
Name() string
// Compress should append the compressed contents
// of src to dst and return the result.
Compress(src, dst []byte) []byte
}
Compressor describes the interface that CompressionWriter needs a compression algorithm to implement.
func Compression ¶
func Compression(name string) Compressor
Compression selects a compression algorithm by name. The returned Compressor will return the same value for Compressor.Name as the specified name.
type Decompressor ¶
type Decompressor interface {
// Name is the name of the compression algorithm.
// See also Compressor.Name.
Name() string
// Decompress decompresses source data
// into dst. It should error out if
// dst is not large enough to fit the
// encoded source data.
//
// It must be safe to make multiple
// calls to Decompress simultaneously
// from different goroutines.
Decompress(src, dst []byte) error
}
Decompressor is the interface that a CompressionReader uses to decompress blocks.
func Decompression ¶
func Decompression(name string) Decompressor
