Functions

func ProbeVolumePlugins

func ProbeVolumePlugins() []volume.VolumePlugin

This is the primary entrypoint for volume plugins.

Types

type MinMaxAllocator

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

func NewMinMaxAllocator

func NewMinMaxAllocator(min, max int) (*MinMaxAllocator, error)

func (*MinMaxAllocator) Allocate

func (a *MinMaxAllocator) Allocate(i int) (bool, error)

func (*MinMaxAllocator) AllocateNext

func (a *MinMaxAllocator) AllocateNext() (int, bool, error)

func (*MinMaxAllocator) Free

func (a *MinMaxAllocator) Free() int

func (*MinMaxAllocator) Has

func (a *MinMaxAllocator) Has(i int) bool

func (*MinMaxAllocator) Release

func (a *MinMaxAllocator) Release(i int) error

func (*MinMaxAllocator) SetRange

func (a *MinMaxAllocator) SetRange(min, max int) error

type Rangeable

type Rangeable interface {
	Allocate(int) (bool, error)
	AllocateNext() (int, bool, error)
	Release(int) error
	Has(int) bool
	Free() int
	SetRange(min, max int) error
}

Rangeable is an Interface that can adjust its min/max range. Rangeable should be threadsafe
