Variables ¶

var (
	ErrInvalidByte           = errors.New("invalid byte")
	ErrInvalidMagicNumber    = errors.New("invalid magic number")
	ErrInvalidVersion        = errors.New("invalid version header")
	ErrInvalidSectionID      = errors.New("invalid section id")
	ErrCustomSectionNotFound = errors.New("custom section not found")
)

var Magic = []byte{0x00, 0x61, 0x73, 0x6D}

Magic is the 4 byte preamble (literally "\0asm") of the binary format See https://www.w3.org/TR/2019/REC-wasm-core-1-20191205/#binary-magic

Functions ¶

func DecodeModule ¶

func DecodeModule(
	binary []byte,
	enabledFeatures api.CoreFeatures,
	memoryLimitPages uint32,
	memoryCapacityFromMax bool,
) (*wasm.Module, error)

DecodeModule implements wasm.DecodeModule for the WebAssembly 1.0 (20191205) Binary Format See https://www.w3.org/TR/2019/REC-wasm-core-1-20191205/#binary-format%E2%91%A0

func EncodeModule ¶

func EncodeModule(m *wasm.Module) (bytes []byte)

EncodeModule implements wasm.EncodeModule for the WebAssembly 1.0 (20191205) Binary Format. Note: If saving to a file, the conventional extension is wasm See https://www.w3.org/TR/2019/REC-wasm-core-1-20191205/#binary-format%E2%91%A0
