Functions

func DecodeInt32

func DecodeInt32(r io.ByteReader) (ret int32, bytesRead uint64, err error)

func DecodeInt33AsInt64

func DecodeInt33AsInt64(r io.ByteReader) (ret int64, bytesRead uint64, err error)

DecodeInt33AsInt64 is a special cased decoder for wasm.BlockType which is encoded as a positive signed integer, yet still needs to fit the 32-bit range of allowed indices. Hence, this is 33, not 32-bit!

See https://webassembly.github.io/spec/core/binary/instructions.html#control-instructions

func DecodeInt64

func DecodeInt64(r io.ByteReader) (ret int64, bytesRead uint64, err error)

func DecodeUint32

func DecodeUint32(r io.ByteReader) (ret uint32, bytesRead uint64, err error)

func EncodeInt32

func EncodeInt32(value int32) []byte

EncodeInt32 encodes the signed value into a buffer in LEB128 format

See https://en.wikipedia.org/wiki/LEB128#Encode_signed_integer

func EncodeInt64

func EncodeInt64(value int64) (buf []byte)
