Types

type Fn

type Fn interface {
	Invoke(context.Context, interface{}) (interface{}, error)
}

Fn represents a function that encapsulates some application functionality.

Fn implementations may contain the functionality directly or facilitate some process by which the functionality is invoked.

func NewFnFromInvokeFunc

func NewFnFromInvokeFunc(i InvokeFunc) Fn

NewFnFromInvokeFunc wraps an InvokeFunc in an Fn and returns the result.

type InvokeFunc

type InvokeFunc func(context.Context, interface{}) (interface{}, error)

InvokeFunc is an adapter to allow the use of ordinary functions as the basis for an Fn.
