Types

type Chan

type Chan struct {
	S chan os.Signal
}

func Exit

func Exit() *Chan

type CpuInfo

type CpuInfo struct {
	User   float64 `json:"user"`
	System float64 `json:"system"`
	Idle   float64 `json:"idle"`
	Nice   float64 `json:"nice"`
}

func Cpu

func Cpu() CpuInfo

type DiskPath

type DiskPath struct {
	Path        string  `json:"path,omitempty"`
	Total       uint64  `json:"total"`
	Free        uint64  `json:"free"`
	Used        uint64  `json:"used"`
	UsedPercent float64 `json:"usedPercent"`
}

func Disk

func Disk() DiskPath

type Event

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

Event represents a one-time event that may occur in the future.

func NewEvent

func NewEvent() *Event

NewEvent returns a new, ready-to-use Event.

func (*Event) Done

func (e *Event) Done() <-chan struct{}

Done returns a channel that will be closed when Fire is called.

func (*Event) Fire

func (e *Event) Fire() bool

Fire causes e to complete. It is safe to call multiple times, and concurrently. It returns true iff this call to Fire caused the signaling channel returned by Done to close.

func (*Event) HasFired

func (e *Event) HasFired() bool

HasFired returns true if Fire has been called.

type IPType

type IPType int8

func GetIPType

func GetIPType(IP net.IP) IPType

type MemInfo

type MemInfo struct {
	// Total amount of RAM on this system
	Total uint64 `json:"total"`

	// RAM available for programs to allocate
	//
	// This value is computed from the kernel specific values.
	Available uint64 `json:"available"`

	// RAM used by programs
	//
	// This value is computed from the kernel specific values.
	Used uint64 `json:"used"`

	// Percentage of RAM used by programs
	//
	// This value is computed from the kernel specific values.
	UsedPercent float64 `json:"usedPercent"`
}

func Mem

func Mem() MemInfo
