Functions

func Get

func Get[T any]() (T, error)

Get retrieves a singleton instance of type T. Returns an error if the instance is not found or type mismatch occurs.

func GetByGroup

func GetByGroup[T any](group string) ([]T, error)

GetByGroup is deprecated, use GetGroup instead. Kept for backward compatibility.

func GetGroup

func GetGroup[T any](group string) ([]T, error)

GetGroup retrieves all singleton instances of type T associated with a group.

func GetGroupWithCtx

func GetGroupWithCtx[T any](ctx context.Context, group string) ([]T, error)

GetGroupWithCtx retrieves all singleton instances of type T associated with a group with context. The context is passed to creator functions if they accept a context parameter.

func GetInstance

func GetInstance[T any]() (T, error)

GetInstance is deprecated, use Get instead. Kept for backward compatibility.

func GetWithCtx

func GetWithCtx[T any](ctx context.Context) (T, error)

GetWithCtx retrieves a singleton instance of type T with context. The context is passed to the creator function if it accepts a context parameter. Returns an error if the instance is not found or type mismatch occurs.

func MustGet

func MustGet[T any]() T

MustGet retrieves a singleton instance of type T, panics on failure. This is useful in init() functions where error handling is not possible.

func MustGetInstance

func MustGetInstance[T any]() T

MustGetInstance is an alias for MustGet, retrieves a singleton instance and panics on failure.

func Register

func Register[T any](creator func() (T, error))

Register registers a factory function for creating singleton instances of type T. The creator function does not receive a context.

func RegisterFactory

func RegisterFactory[T any](creator func() (T, error))

RegisterFactory is deprecated, use Register instead. Kept for backward compatibility.

func RegisterGroup

func RegisterGroup[T any](group string, creator func() (T, error))

RegisterGroup registers a factory function and associates it with a group. The creator function does not receive a context.

func RegisterGroupWithCtx

func RegisterGroupWithCtx[T any](group string, creator func(context.Context) (T, error))

RegisterGroupWithCtx registers a factory function that accepts a context and associates it with a group. The context will be passed when the instance is created.

func RegisterWithCtx

func RegisterWithCtx[T any](creator func(context.Context) (T, error))

RegisterWithCtx registers a factory function that accepts a context parameter. The context will be passed when the instance is created.
