type MinMaxAllocator added in v1.6.0

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

MinMaxAllocator defines allocator struct.

func NewMinMaxAllocator added in v1.6.0

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

NewMinMaxAllocator return a new allocator or error based on provided min/max value.

func (*MinMaxAllocator) Allocate added in v1.6.0

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

Allocate allocates provided value in the allocator and mark it as used.

func (*MinMaxAllocator) AllocateNext added in v1.6.0

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

AllocateNext allocates next value from the allocator.

func (*MinMaxAllocator) Free added in v1.6.0

func (a *MinMaxAllocator) Free() int

Free returns the number of free values in the allocator.

func (*MinMaxAllocator) Has added in v1.6.0

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

Has check whether the provided value is used in the allocator

func (*MinMaxAllocator) Release added in v1.6.0

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

Release free/delete provided value from the allocator.

func (*MinMaxAllocator) SetRange added in v1.6.0

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

SetRange defines the range/pool with provided min and max values.

type Rangeable added in v1.6.0

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
