Types

type ExtensionCaller

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

ExtensionCaller calls extension functions

func (*ExtensionCaller) Call

func (ec *ExtensionCaller) Call(args ...reflect.Value) (reflect.Value, error)

}

Host implements an extension host that handles registering extensions and executing them.

func NewHost

func NewHost() *Host
