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)
