Returns

Ok(()) if the provider was added, or Err(Provider) if there is a provider registered for that type.

pub fn add_singleton<T>(&mut self, value: T) -> Result<(), Provider<'_>> where
    T: Send + Sync + 'static,

Returns

Ok(()) if the provider was added, or Err(Provider) if there is a provider registered for that type.

pub fn add_deps_fn_with_name<T, F>(
    &mut self,
    name: &str,
    f: F
) -> Result<(), Provider<'_>> where
    T: Send + Sync + 'static,
    F: Fn(&Container<'_>) -> T + Send + Sync + 'static,

Returns

Ok(()) if the provider was added, or Err(Provider) if there is a provider registered for that type.

pub fn get<T>(&self) -> Option<Resolved<T>> where
    T: Send + Sync + 'static, 

Returns a value registered for the given type or None if no provider is register for the given type.

The returning value could be either scoped or a singleton.

pub fn get_with_name<T>(&self, name: &str) -> Option<Resolved<T>> where
    T: Send + Sync + 'static, 

Returns a value registered for the given type and name or None if no provider is register for the given type.

The returning value could be either scoped or a singleton.
