pub struct Singleton<T> { /* private fields */ }

Singleton dependencies.

This dependency is created only once for the specified registry. It’s created lazily on-demand.

Implementations

impl<T> Singleton<T>

where T: RegisterableSingleton,

pub fn get(self) -> Arc<T>

Access the inner dependency, returns a ref-counted object.

impl<T> Debug for Singleton<T>

where T: Debug,

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result<(), Error>

impl<T> Dep for Singleton<T>

where T: RegisterableSingleton,

fn new(registry: &Registry) -> Singleton<T>

Create a new Singleton.

Panic
