Functions ¶
func VarFieldSize ¶
VarFieldSize returns the size of a varible field variable ([]byte, string and unicode variants).
Types ¶
type Decoder ¶
type Decoder struct {
// contains filtered or unexported fields
}
Decoder decodes hdb protocol datatypes on basis of an io.Reader.
func NewDecoder ¶
func NewDecoder(rd io.Reader, decoder func() transform.Transformer) *Decoder
NewDecoder creates a new Decoder instance based on an io.Reader.
func (*Decoder) CESU8Bytes ¶
CESU8Bytes decodes CESU-8 into UTF-8 bytes. - error is only returned in case of conversion errors.
func (*Decoder) CESU8LIBytes ¶
CESU8LIBytes decodes CESU-8 into UTF-8 bytes with length indicator.
func (*Decoder) CESU8LIString ¶
CESU8LIString decodes a CESU-8 into a UTF-8 string with length indicator.
func (*Decoder) Decimal ¶
Decimal decodes a decimal. - error is only returned in case of conversion errors.
func (*Decoder) ResetError ¶
ResetError return and resets reader error.
func (*Decoder) Uint16ByteOrder ¶
Uint16ByteOrder decodes an uint16 in given byte order.
func (*Decoder) Uint32ByteOrder ¶
Uint32ByteOrder decodes an uint32 in given byte order.
type Encoder ¶
type Encoder struct {
// contains filtered or unexported fields
}
Encoder encodes hdb protocol datatypes on basis of an io.Writer.
func NewEncoder ¶
func NewEncoder(wr io.Writer, encoder func() transform.Transformer) *Encoder
NewEncoder creates a new Encoder instance.
func (*Encoder) CESU8Bytes ¶
CESU8Bytes encodes UTF-8 bytes into CESU-8 and returns the CESU-8 bytes written.
func (*Encoder) CESU8LIBytes ¶
CESU8LIBytes encodes UTF-8 into CESU-8 bytes with length indicator.
func (*Encoder) CESU8LIString ¶
CESU8LIString encodes an UTF-8 into a CESU-8 string with length indicator.
func (*Encoder) CESU8String ¶
CESU8String encodes an UTF-8 string into CESU-8 and returns the CESU-8 bytes written.
func (*Encoder) Uint16ByteOrder ¶
Uint16ByteOrder encodes an uint16 in given byte order.
