Enum dilib::Shared

pub enum Shared<'a> {
    Instance(Arc<dyn Any + Send + Sync>),
    Lazy(Arc<LateInit<Arc<dyn Any + Send + Sync>, &'a Container<'a>, Box<dyn FnOnce(&Container<'_>) -> Arc<dyn Any + Send + Sync> + Send + Sync>>>),
}

Provides a singleton value.

Variants

Instance(Arc<dyn Any + Send + Sync>)

A single instance of the value.

Lazy(Arc<LateInit<Arc<dyn Any + Send + Sync>, &'a Container<'a>, Box<dyn FnOnce(&Container<'_>) -> Arc<dyn Any + Send + Sync> + Send + Sync>>>)

A factory function to create the single value.

Implementations

impl<'a> Shared<'a>

pub fn new<T>(value: T) -> Self where
    T: Send + Sync + 'static, 

Provides a new instance of the singleton.

pub fn new_lazy<T, F>(f: F) -> Self where
    T: Send + Sync + 'static,
    F: FnOnce(&Container<'_>) -> T + Send + Sync + 'static, 

Provides a new instance of the singleton from a factory.

Trait Implementations

impl<'a> Clone for Shared<'a>

fn clone(&self) -> Shared<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
