func Register(name string)

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

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 (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 (h *Hook[Func]) GetOk() (f Func, ok bool)

GetOk returns the hook function and true if it has been set, otherwise its zero value and false.

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

IsSet reports whether the hook has been 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.

type Hooks[Func any] []Func

Hooks is a slice of funcs.

As opposed to a single Hook, this is meant to be used when multiple parties are able to install the same hook.

func (h *Hooks[Func]) Add(f Func)

Add adds a hook to the list of hooks.

Add should only be called during early program startup before Tailscale has started. It is not safe for concurrent use.
