Functions

func NewReader

func NewReader(t testing.TB, r io.Reader) io.ReadCloser

NewReader creates a new ReadCloser. Reads from the returned ReadCloser read and decompress data from r. If r does not implement io.ByteReader, the decompressor may read more data than necessary from r. It is the caller's responsibility to call Close on the ReadCloser when done.

The io.ReadCloser returned by NewReader also implements [Resetter].

func NewReaderDict

func NewReaderDict(t testing.TB, r io.Reader, dict []byte) io.ReadCloser

NewReaderDict is like NewReader but uses a preset dictionary. NewReaderDict ignores the dictionary if the compressed data does not refer to it. If the compressed data refers to a different dictionary, NewReaderDict returns [ErrDictionary].

The ReadCloser returned by NewReaderDict also implements [Resetter].

func NewWriterLevel

func NewWriterLevel(t testing.TB, w io.Writer, level int) *zlib.Writer

NewWriterLevel is like NewWriter but specifies the compression level instead of assuming DefaultCompression.

The compression level can be DefaultCompression, NoCompression, HuffmanOnly or any integer value between BestSpeed and BestCompression inclusive. The error returned will be nil if the level is valid.

func NewWriterLevelDict

func NewWriterLevelDict(t testing.TB, w io.Writer, level int, dict []byte) *zlib.Writer

NewWriterLevelDict is like NewWriterLevel but specifies a dictionary to compress with.

The dictionary may be nil. If not, its contents should not be modified until the Writer is closed.
