Functions

func Every

func Every(ctx context.Context, d time.Duration, work func(t time.Time))

Runs a given work function every "d" duration until the provided context is canceled.

func FirstNotEmpty

func FirstNotEmpty(v ...string) string

FirstNotEmpty returns the first string passed in that is not an empty value.

func FormatBytes

func FormatBytes(b int64) string

func MustInt

func MustInt(v string) int

func ScanReader

func ScanReader(r io.Reader, callback func(line []byte)) error

Types

type AtomicBool

type AtomicBool struct {
	// contains filtered or unexported fields
}

func NewAtomicBool

func NewAtomicBool(v bool) *AtomicBool

func (*AtomicBool) Load

func (ab *AtomicBool) Load() bool

func (*AtomicBool) MarshalJSON

func (ab *AtomicBool) MarshalJSON() ([]byte, error)

func (*AtomicBool) Store

func (ab *AtomicBool) Store(v bool)

func (*AtomicBool) SwapIf

func (ab *AtomicBool) SwapIf(v bool) bool

Stores the value "v" if the current value stored in the AtomicBool is the opposite boolean value. If successfully swapped, the response is "true", otherwise "false" is returned.

func (*AtomicBool) UnmarshalJSON

func (ab *AtomicBool) UnmarshalJSON(b []byte) error

type AtomicString

type AtomicString struct {
	// contains filtered or unexported fields
}

AtomicString allows for reading/writing to a given struct field without having to worry about a potential race condition scenario. Under the hood it uses a simple sync.RWMutex to control access to the value.

func NewAtomicString

func NewAtomicString(v string) *AtomicString

func (*AtomicString) Load

func (as *AtomicString) Load() string

Loads the string value and returns it.

func (*AtomicString) MarshalJSON

func (as *AtomicString) MarshalJSON() ([]byte, error)

func (*AtomicString) Store

func (as *AtomicString) Store(v string)

Stores the string value passed atomically.

func (*AtomicString) UnmarshalJSON

func (as *AtomicString) UnmarshalJSON(b []byte) error

type Information

type Information struct {
	Version       string `json:"version"`
	KernelVersion string `json:"kernel_version"`
	Architecture  string `json:"architecture"`
	OS            string `json:"os"`
	CpuCount      int    `json:"cpu_count"`
}

func GetSystemInformation

func GetSystemInformation() (*Information, error)
