Types

type Func

type Func func(key string, done <-chan struct{}) (interface{}, error)

Func is the type of the function to memoize

type Memo

	// contains filtered or unexported fields
}

A Memo caches the results of calling a Func.

func New

func New(f Func) *Memo

func (*Memo) Close

func (memo *Memo) Close()

func (*Memo) Get

func (memo *Memo) Get(key string, done <-chan struct{}) (interface{}, error)

Get is concurrency safe
