Functions ¶
func ConsumeBytes ¶
ConsumeBytes reads and throws away a number of bytes from r, returning the number of bytes it consumed.
func ReadInt ¶
ReadInt reads a signed integer of either 8, 16, 32 or 64 bits from r, returning the result as a int64.
func ReadUint ¶
ReadUint reads an unsigned integer of either 8, 16, 32 or 64 bits from r, returning the result as a uint64.
func WriteBytes ¶
WriteBytes writes the given v for count times to writer w.
Types ¶
type BitStream ¶
type BitStream struct {
Data []byte // The byte slice containing the bits
ReadPos uint32 // The current read offset from the start of the Data slice (in bits)
WritePos uint32 // The current write offset from the start of the Data slice (in bits)
}
BitStream provides methods for reading and writing bits to a slice of bytes. Bits are packed in a least-significant-bit to most-significant-bit order.
func (*BitStream) CanRead ¶ added in v0.6.2
CanRead returns true if there's enough data to call Read(count).
func (*BitStream) Read ¶
Read reads the specified number of bits from the BitStream, increamenting the ReadPos by the specified number of bits and returning the bits packed into a uint64. The bits are packed into the uint64 from LSB to MSB.
func (*BitStream) ReadBit ¶
ReadBit reads a single bit from the BitStream, incrementing ReadPos by one.
type Readable ¶
type Readable interface {
// ReadSimple is invoked by a Reader to read the POD.
ReadSimple(Reader)
}
Readable is the interface to things that readable as Plain Old Data.
type Reader ¶
type Reader interface {
io.Reader
// Data reads the data bytes in their entirety.
Data([]byte)
// Bool decodes and returns a boolean value from the Reader.
Bool() bool
// Int8 decodes and returns a signed, 8 bit integer value from the Reader.
Int8() int8
// Uint8 decodes and returns an unsigned, 8 bit integer value from the Reader.
Uint8() uint8
// Int16 decodes and returns a signed, 16 bit integer value from the Reader.
Int16() int16
// Uint16 decodes and returns an unsigned, 16 bit integer value from the Reader.
Uint16() uint16
// Int32 decodes and returns a signed, 32 bit integer value from the Reader.
Int32() int32
// Uint32 decodes and returns an unsigned, 32 bit integer value from the Reader.
Uint32() uint32
// Float16 decodes and returns a 16 bit floating-point value from the Reader.
Float16() f16.Number
// Float32 decodes and returns a 32 bit floating-point value from the Reader.
Float32() float32
// Int64 decodes and returns a signed, 64 bit integer value from the Reader.
Int64() int64
// Uint64 decodes and returns an unsigned, 64 bit integer value from the Reader.
Uint64() uint64
// Float64 decodes and returns a 64 bit floating-point value from the Reader.
Float64() float64
// String decodes and returns a string from the Reader.
String() string
// Simple decodes a Readable type from the Writer.
Simple(Readable)
// Decode a collection count from the stream.
Count() uint32
// If there is an error reading any input, all further reading returns the
// zero value of the type read. Error() returns the error which stopped
// reading from the stream. If reading has not stopped it returns nil.
Error() error
// Set the error state and stop reading from the stream.
SetError(error)
}
Reader provides methods for decoding values.
type Writable ¶
type Writable interface {
// WriteSimple is invoked by a Writer to write the POD.
WriteSimple(Writer)
}
Writable is the interface to things that are writable as Plain Old Data.
type Writer ¶
type Writer interface {
// Data writes the data bytes in their entirety.
Data([]byte)
// Bool encodes a boolean value to the Writer.
Bool(bool)
// Int8 encodes a signed, 8 bit integer value to the Writer.
Int8(int8)
// Uint8 encodes an unsigned, 8 bit integer value to the Writer.
Uint8(uint8)
// Int16 encodes a signed, 16 bit integer value to the Writer.
Int16(int16)
// Uint16 encodes an unsigned, 16 bit integer value to the Writer.
Uint16(uint16)
// Int32 encodes a signed, 32 bit integer value to the Writer.
Int32(int32)
// Uint32 encodes an usigned, 32 bit integer value to the Writer.
Uint32(uint32)
// Float16 encodes a 16 bit floating-point value to the Writer.
Float16(f16.Number)
// Float32 encodes a 32 bit floating-point value to the Writer.
Float32(float32)
// Int64 encodes a signed, 64 bit integer value to the Writer.
Int64(int64)
// Uint64 encodes an unsigned, 64 bit integer value to the Encoders's io.Writer.
Uint64(uint64)
// Float64 encodes a 64 bit floating-point value to the Writer.
Float64(float64)
// String encodes a string to the Writer.
String(string)
// Simple encodes a Writable type to the Writer.
Simple(Writable)
// If there is an error writing any output, all further writing becomes
// a no-op. Error() returns the error which stopped writing to the stream.
// If writing has not stopped it returns nil.
Error() error
// Set the error state and stop writing to the stream.
SetError(error)
}
Writer provides methods for encoding values.
