Functions ¶
func AsSerializable ¶
func AsSerializable(se Serializable, data []byte) error
func ToArray ¶
func ToArray(se Serializable) ([]byte, error)
Types ¶
type BinaryReader ¶
type BinaryReader struct {
Err error
// contains filtered or unexported fields
}
BinaryReader is a convenient wrapper around a io.Reader and err object. Used to simplify error handling when reading into a struct with many fields.
func NewBinaryReaderFromBuf ¶
func NewBinaryReaderFromBuf(b []byte) *BinaryReader
NewBinaryReaderFromBuf makes a BinaryReader from byte buffer.
func NewBinaryReaderFromIO ¶
func NewBinaryReaderFromIO(ior io.Reader) *BinaryReader
NewBinaryReaderFromIO makes a BinaryReader from io.Reader.
func (*BinaryReader) ReadBE ¶
func (r *BinaryReader) ReadBE(v interface{})
ReadBE reads from the underlying io.Reader into the interface v in big-endian format.
func (*BinaryReader) ReadBytesWithGrouping ¶
func (reader *BinaryReader) ReadBytesWithGrouping() (key []byte, err error)
ReadBytesWithGrouping ...
func (*BinaryReader) ReadLE ¶
func (r *BinaryReader) ReadLE(v interface{})
ReadLE reads from the underlying io.Reader into the interface v in little-endian format.
func (*BinaryReader) ReadUnit64Bytes ¶
func (r *BinaryReader) ReadUnit64Bytes() []byte
ReadUnit64Bytes reads from the underlying io.Reader into the interface v in little-endian format
func (*BinaryReader) ReadVarBytes ¶
func (r *BinaryReader) ReadVarBytes() []byte
ReadVarBytes reads the next set of bytes from the underlying reader. ReadVarUInt() is used to determine how large that slice is
func (*BinaryReader) ReadVarString ¶
func (r *BinaryReader) ReadVarString() string
ReadVarString calls ReadVarBytes and casts the results as a string.
func (*BinaryReader) ReadVarUint ¶
func (r *BinaryReader) ReadVarUint() uint64
ReadVarUint reads a variable-length-encoded integer from the underlying reader.
type BinaryWriter ¶
type BinaryWriter struct {
Err error
// contains filtered or unexported fields
}
BinaryWriter is a convenient wrapper around a io.Writer and err object. Used to simplify error handling when writing into a io.Writer from a struct with many fields.
func NewBinaryWriterFromIO ¶
func NewBinaryWriterFromIO(iow io.Writer) *BinaryWriter
NewBinaryWriterFromIO makes a BinaryWriter from io.Writer.
func (*BinaryWriter) WriteBE ¶
func (w *BinaryWriter) WriteBE(v interface{})
WriteBE writes into the underlying io.Writer from an object v in big-endian format.
func (*BinaryWriter) WriteBytesWithGrouping ¶
func (writer *BinaryWriter) WriteBytesWithGrouping(value []byte)
WriteBytesWithGrouping ...
func (*BinaryWriter) WriteLE ¶
func (w *BinaryWriter) WriteLE(v interface{})
WriteLE writes into the underlying io.Writer from an object v in little-endian format.
func (*BinaryWriter) WriteVarBytes ¶
func (w *BinaryWriter) WriteVarBytes(b []byte)
WriteVarBytes writes a variable length byte array into the underlying io.Writer.
func (*BinaryWriter) WriteVarString ¶
func (w *BinaryWriter) WriteVarString(s string)
WriteVarString writes a variable length string into the underlying io.Writer.
func (*BinaryWriter) WriteVarUint ¶
func (w *BinaryWriter) WriteVarUint(val uint64)
WriteVarUint writes a uint64 into the underlying writer using variable-length encoding.
type BufBinaryWriter ¶
type BufBinaryWriter struct {
*BinaryWriter
// contains filtered or unexported fields
}
BufBinaryWriter is an additional layer on top of BinaryWriter that automatically creates buffer to write into that you can get after all writes via Bytes().
func NewBufBinaryWriter ¶
func NewBufBinaryWriter() *BufBinaryWriter
NewBufBinaryWriter makes a BufBinaryWriter with an empty byte buffer.
func (*BufBinaryWriter) Bytes ¶
func (bw *BufBinaryWriter) Bytes() []byte
Bytes returns resulting buffer and makes future writes return an error.
func (*BufBinaryWriter) Reset ¶
func (bw *BufBinaryWriter) Reset()
Reset resets the state of the buffer, making it usable again. It can make buffer usage somewhat more efficient, because you don't need to create it again, but beware that the buffer is gonna be the same as the one returned by Bytes(), so if you need that data after Reset() you have to copy it yourself.
type Serializable ¶
type Serializable interface {
Deserialize(*BinaryReader)
Serialize(*BinaryWriter)
}
Serializable defines the binary encoding/decoding interface. Errors are returned via BinaryReader/BinaryWriter Err field. These functions must have safe behavior when passed BinaryReader/BinaryWriter with Err already set. Invocations to these functions tend to be nested, with this mechanism only the top-level caller should handle the error once and all the other code should just not panic in presence of error.
