func IsWASIError

func IsWASIError(err error) (Errno, bool)

IsWASIError detects and unwraps a WASIError to its component parts.

func (Errno) String

func (e Errno) String() string

String implements fmt.Stringer.

type WASIError

type WASIError struct {
	Errno Errno
}

WASIError decorates error-class Errno values and implements the error interface.

Note that TinyGo currently doesn't support errors.As. Callers can use the IsWASIError helper instead.

func (WASIError) Error

func (e WASIError) Error() string

Error implements the error interface.
