Types

type AfterPreloader

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

AfterPreloader is embedded in a Preloader to chain loading whenever a preloaded object is scanned, it should be collected with the Collect method The loading functions should be added with AppendLoader later, when this object is called like any other bob.Loader, it calls the appended loaders with the collected objects

func NewAfterPreloader

func NewAfterPreloader[T any, Ts ~[]T]() *AfterPreloader

NewAfterPreloader returns a new AfterPreloader based on the given types

func (*AfterPreloader) AppendLoader

func (a *AfterPreloader) AppendLoader(fs ...bob.Loader)

func (*AfterPreloader) Collect

func (a *AfterPreloader) Collect(v any) error

func (*AfterPreloader) Load

func (a *AfterPreloader) Load(ctx context.Context, exec bob.Executor, _ any) error
