Types

type AfterPreloader added in v0.13.0 

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 added in v0.13.0 

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

NewAfterPreloader returns a new AfterPreloader based on the given types

func (*AfterPreloader) AppendLoader added in v0.13.0 

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

func (*AfterPreloader) Collect added in v0.13.0 

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

func (*AfterPreloader) Load added in v0.13.0 

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

type EditRule added in v0.32.0 

type EditRule interface {
	// contains filtered or unexported methods
}

func RecordPoints added in v0.32.0 

func RecordPoints(oldStart, oldEnd int, callbacks ...func(start, end int) error) []EditRule

type Loader added in v0.19.0 

type Loader[Q loadable] func(ctx context.Context, exec bob.Executor, retrieved any) error

Loader builds a query mod that makes an extra query after the object is retrieved it can be used to prevent N+1 queries by loading relationships in batches

func (Loader[Q]) Apply added in v0.19.0 

func (l Loader[Q]) Apply(q Q)

Apply satisfies the bob.Mod[Q] interface

func (Loader[Q]) Load added in v0.19.0 

func (l Loader[Q]) Load(ctx context.Context, exec bob.Executor, retrieved any) error

Load is called after the original object is retrieved

func (Loader[Q]) ModifyPreloadSettings added in v0.19.0 

func (l Loader[Q]) ModifyPreloadSettings(s *PreloadSettings[Q])

modifyPreloader makes a Loader also work as a mod for a Preloader

func (e OutOfBoundsError) Error() string

func (OutOfBoundsError) Is added in v0.32.0 

func (e OutOfBoundsError) Is(target error) bool

type PreloadOption[Q loadable] interface {
	ModifyPreloadSettings(*PreloadSettings[Q])
}

type PreloadSettings added in v0.19.0 

type PreloadSettings[Q loadable] struct {
	Columns     []string
	SubLoaders  []Preloader[Q]
	ExtraLoader *AfterPreloader
	Mods        [][]preloadfilter
	Alias       string
}

func NewPreloadSettings added in v0.19.0 

func NewPreloadSettings[T any, Ts ~[]T, Q loadable](cols []string) PreloadSettings[Q]

func (PreloadWhere[Q]) ModifyPreloadSettings added in v0.20.0 

func (filters PreloadWhere[Q]) ModifyPreloadSettings(el *PreloadSettings[Q])

type Preloadable added in v0.19.0 

type Preloadable interface {
	Preload(name string, rel any) error
}

type Preloader added in v0.19.0 

type Preloader[Q loadable] func(parent string) (bob.Mod[Q], scan.MapperMod, []bob.Loader)

Preloader builds a query mod that modifies the original query to retrieve related fields while it can be used as a queryMod, it does not have any direct effect. if using manually, the ApplyPreload method should be called with the query's context AFTER other mods have been applied

func (Preloader[Q]) Apply added in v0.19.0 

func (l Preloader[Q]) Apply(q Q)

Apply satisfies bob.Mod[*dialect.SelectQuery]. 1. It modifies the query to join the preloading table and the extra columns to retrieve 2. It modifies the mapper to scan the new columns. 3. It calls the original object's Preload method with the loaded object

func (Preloader[Q]) ModifyPreloadSettings added in v0.19.0 

func (l Preloader[Q]) ModifyPreloadSettings(s *PreloadSettings[Q])

modifyPreloader makes a Loader also work as a mod for a Preloader
