type Builder ¶

type Builder[T any] func(sequence uint64) *T

Builder constructs an entity for a one-based sequence number.

type Factory ¶

type Factory[T any] struct {
	// contains filtered or unexported fields
}

func New[T any](builder Builder[T], persister Persister[T]) (*Factory[T], error)

func (factory *Factory[T]) Build(traits ...Trait[T]) (*T, error)

func (factory *Factory[T]) BuildList(count int, traits ...Trait[T]) ([]*T, error)

func (factory *Factory[T]) Create(ctx context.Context, traits ...Trait[T]) (*T, error)

func (factory *Factory[T]) CreateList(ctx context.Context, count int, traits ...Trait[T]) ([]*T, error)

type Persister ¶

type Persister[T any] func(context.Context, *T) error

Persister stores an entity. Applications normally adapt a repository Create method here instead of coupling factories to a persistence implementation.

type Trait ¶

type Trait[T any] func(*T)

Trait applies an explicit variation to a built entity.
