Types

type Pool

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

Pool is a small pool of recently returned objects. Unlike sync.Pool, the pool is not subject to gargbage collection under memory pressure.

func New

func New(makeNew func() interface{}, clean func(v interface{})) *Pool

New returns a new free pool.

func (*Pool) Return

func (p *Pool) Return(v interface{})

Return returns an item to the pool after cleaning it.

func (*Pool) Take

func (p *Pool) Take() interface{}

Take returns an item from the pool, and if not available makes a new one.
