DecodeBigIntArray decodes a byte array to an array of *big.Ints

func (*Decoder) DecodeBool

func (sd *Decoder) DecodeBool() (bool, error)

DecodeBool accepts a byte array representing a SCALE encoded bool and performs SCALE decoding of the bool then returns it. if invalid, return false and an error

func (*Decoder) DecodeBoolArray

func (sd *Decoder) DecodeBoolArray() ([]bool, error)

DecodeBoolArray decodes a byte array to an array of bools

func (*Decoder) DecodeByteArray

func (sd *Decoder) DecodeByteArray() (o []byte, err error)

DecodeByteArray accepts a byte array representing a SCALE encoded byte array and performs SCALE decoding of the byte array if the encoding is valid, it then returns the decoded byte array, the total number of input bytes decoded, and nil otherwise, it returns nil, 0, and error

func (*Decoder) DecodeCustom

func (sd *Decoder) DecodeCustom(t interface{}) (interface{}, error)

DecodeCustom check if interface has method Decode(io.Reader), if so use that, otherwise use regular scale decoding

func (*Decoder) DecodeFixedWidthInt

func (sd *Decoder) DecodeFixedWidthInt(t interface{}) (o interface{}, err error)

DecodeFixedWidthInt decodes integers < 2**32 by reading the bytes in little endian

func (*Decoder) DecodeIntArray

func (sd *Decoder) DecodeIntArray() ([]int, error)

DecodeIntArray decodes a byte array to an array of ints

func (*Decoder) DecodeInteger

func (sd *Decoder) DecodeInteger() (_ int64, err error)

DecodeInteger accepts a byte array representing a SCALE encoded integer and performs SCALE decoding of the int if the encoding is valid, it then returns (o, bytesDecoded, err) where o is the decoded integer, bytesDecoded is the number of input bytes decoded, and err is nil otherwise, it returns 0, 0, and error

func (*Decoder) DecodeInterface

func (sd *Decoder) DecodeInterface(t interface{}) (interface{}, error)

DecodeInterface will decode to interface

func (*Decoder) DecodePtr

func (sd *Decoder) DecodePtr(t interface{}) (err error)

DecodePtr is the high level function wrapping the specific type decoding functions The results of decode are written to t interface by reference (instead of returning

value as Decode does)

func (*Decoder) DecodePtrBigInt

func (sd *Decoder) DecodePtrBigInt(output *big.Int) (err error)

DecodePtrBigInt decodes a SCALE encoded byte array into a *big.Int

Changes the value of output to decoded value

Works for all integers, including ints > 2**64

func (*Decoder) DecodePtrBigIntArray

func (sd *Decoder) DecodePtrBigIntArray(output interface{}) error

DecodePtrBigIntArray decodes a byte array to an array of *big.Ints

writes value to output by reference

func (*Decoder) DecodePtrBool

func (sd *Decoder) DecodePtrBool(output interface{}) error

DecodePtrBool accepts a byte array representing a SCALE encoded bool and performs SCALE decoding of the bool then writes the result to output via reference. if invalid, false and an error

func (*Decoder) DecodePtrBoolArray

func (sd *Decoder) DecodePtrBoolArray(output interface{}) error

DecodePtrBoolArray decodes a byte array to an array of bools that is written to output by reference

func (*Decoder) DecodePtrByteArray

func (sd *Decoder) DecodePtrByteArray(output interface{}) error

DecodePtrByteArray accepts a byte array representing a SCALE encoded byte array and performs SCALE decoding of the byte array

func (*Decoder) DecodePtrFixedWidthInt

func (sd *Decoder) DecodePtrFixedWidthInt(t interface{}) (err error)

func (*Decoder) DecodeTuple

func (sd *Decoder) DecodeTuple(t interface{}) (interface{}, error)

DecodeTuple accepts a byte array representing the SCALE encoded tuple and an interface. This interface should be a pointer to a struct which the encoded tuple should be marshaled into. If it is a valid encoding for the struct, it returns the decoded struct, otherwise error, Note that we return the same interface that was passed to this function; this is because we are writing directly to the struct that is passed in, using reflect to get each of the fields.
