Functions

func Register

func Register(name string)

Register notes that the named feature is linked into the binary.

Types

type Hook

type Hook[Func any] struct {
	// contains filtered or unexported fields
}

Hook is a func that can only be set once.

It is not safe for concurrent use.

func (*Hook[Func]) Get

func (h *Hook[Func]) Get() Func

Get returns the hook function, or panics if it hasn't been set. Use IsSet to check if it's been set.

func (*Hook[Func]) IsSet

func (h *Hook[Func]) IsSet() bool

IsSet reports whether the hook has been set.

func (*Hook[Func]) Set

func (h *Hook[Func]) Set(f Func)

Set sets the hook function, panicking if it's already been set or f is the zero value.

It's meant to be called in init.
