Functions ¶

func Aligned8Byte ¶

func Aligned8Byte(fields []FieldOffset, out io.Writer) bool

Aligned8Byte returns if all fields are aligned modulo 8-bytes.

Error messaging is printed to out for any fileds determined misaligned.

func NewTestError ¶

func NewTestError(s string) error

Types ¶

type Env ¶

type Env struct {
	Name   string
	Value  string
	Exists bool
}

type EnvStore ¶

type EnvStore interface {
	// Records the environment variable into the store.
	Record(key string)

	// Restore recovers the environment variables in the store.
	Restore() error
}

EnvStore stores and recovers environment variables.

func NewEnvStore ¶

func NewEnvStore() EnvStore

func SetEnvVariables ¶

func SetEnvVariables(env map[string]string) (EnvStore, error)

type FieldOffset ¶

type FieldOffset struct {
	// Name of the field.
	Name string

	// Offset of the field in bytes.
	//
	// To compute this at compile time use unsafe.Offsetof.
	Offset uintptr
}

FieldOffset is a preprocessor representation of a struct field alignment.

type TestError ¶

type TestError string

func (TestError) Error ¶

func (e TestError) Error() string
