Variables

var BinarySerializer binaryFreeList = make(chan []byte, binaryFreeListMaxItems)

BinarySerializer provides a free list of buffers to use for serializing and deserializing primitive integer values to and from io.Readers and io.Writers.

Functions

func VarIntSerializeSize

func VarIntSerializeSize(val uint64) int

VarIntSerializeSize returns the number of bytes it would take to serialize val as a variable length integer.

func VarSliceSerializeSize

func VarSliceSerializeSize(val []byte) int

VarSliceSerializeSize returns the number of bytes it would take to serialize val as a variable length byte slice.

Types

type Deserializer

type Deserializer struct {
	// contains filtered or unexported fields
}

Deserializer implements methods that help to deserialize an Elements transaction.

func NewDeserializer

func NewDeserializer(buffer *bytes.Buffer) *Deserializer

NewDeserializer returns an instance of Deserializer.

func (*Deserializer) ReadElementsAsset

func (d *Deserializer) ReadElementsAsset() ([]byte, error)

ReadElementsAsset reads an Elements output asset form the reader's buffer

func (*Deserializer) ReadElementsNonce

func (d *Deserializer) ReadElementsNonce() ([]byte, error)

ReadElementsNonce reads a maybe non-zero Elements output nonce form the reader's buffer

func (*Deserializer) ReadElementsValue

func (d *Deserializer) ReadElementsValue() ([]byte, error)

ReadElementsValue reads the first byte to determine if the value is confidential or unconfidential, then reads the right number of bytes accordingly.

func (*Deserializer) ReadSlice

func (d *Deserializer) ReadSlice(n uint) ([]byte, error)

ReadSlice reads the next n bytes from the reader's buffer

func (*Deserializer) ReadToEnd

func (d *Deserializer) ReadToEnd() []byte

ReadToEnd returns bytes left in buffer

func (*Deserializer) ReadUint16

func (d *Deserializer) ReadUint16() (uint16, error)

ReadUint16 reads a uint16 value from reader's buffer.

func (*Deserializer) ReadUint32

func (d *Deserializer) ReadUint32() (uint32, error)

ReadUint32 reads a uint32 value from reader's buffer.

func (*Deserializer) ReadUint64

func (d *Deserializer) ReadUint64() (uint64, error)

ReadUint64 reads a uint64 value from reader's buffer.

func (*Deserializer) ReadUint8

func (d *Deserializer) ReadUint8() (uint8, error)

ReadUint8 reads a uint8 value from reader's buffer.

func (*Deserializer) ReadVarInt

func (d *Deserializer) ReadVarInt() (uint64, error)

ReadVarInt reads a variable length integer from reader's buffer and returns it as a uint64.

func (*Deserializer) ReadVarSlice

func (d *Deserializer) ReadVarSlice() ([]byte, error)

ReadVarSlice first reads the length n of the bytes, then reads the next n bytes

func (*Deserializer) ReadVector

func (d *Deserializer) ReadVector() ([][]byte, error)

ReadVector reads the length n of the array of bytes, then reads the next n array bytes

type Serializer

type Serializer struct {
	// contains filtered or unexported fields
}

Serializer implements methods that help to serialize an Elements transaction.
