  dir: String,
) -> Builder(a, HasDirectories, c)

</>

pub fn new() -> Builder(Nil, NoDirectories, NoInitializer)

Construct a new builder

</>

pub fn on_reload(
  builder: Builder(a, b, c),
  callback: fn(a, String) -> a,
) -> Builder(a, b, c)

Add a callback to be run after reload

pub fn set_initializer(
  builder: Builder(a, b, NoInitializer),
  initializer: fn() -> a,
) -> Builder(a, b, HasInitializer)

Add an initializer

This will be run in the file watcher process, so it can be useful to, for example, add state to an actor

pub fn start(
  builder: Builder(Nil, HasDirectories, NoInitializer),
) -> Result(Subject(Change), StartError)

Start reloader, if no state has been set

</>

pub fn start_state(
  builder: Builder(a, HasDirectories, HasInitializer),
) -> Result(Subject(Change), StartError)

Start reloader, ensuring that a state has been set
