}

Fields

registry: &'static Registry

stores: Mutex<HashMap<(TypeId, String), Box<dyn Any + Send + Sync>>>

Implementations

impl Composition

pub fn new(registry: &'static Registry) -> Self

The given registry will be used for creation of anonymous stores during composition

pub fn extend_with_configs<T: ?Sized + Send + Sync + 'static>( &mut self, configs: HashMap<String, DeserializeWithRegistry<Box<dyn ServiceBuilder<Output = T>>>>, )

pub async fn build<T: ?Sized + Send + Sync + 'static>( &self, entrypoint: &str, ) -> Result<Arc<T>, CompositionError>

Looks up the entrypoint name in the composition and returns an instantiated service.

pub fn context(&self) -> CompositionContext<'_>

Trait Implementations

impl<T: ?Sized + Send + Sync + 'static> Extend<(String, DeserializeWithRegistry<Box<dyn ServiceBuilder<Output = T>>>)> for Composition

fn extend<I>(&mut self, configs: I)

where I: IntoIterator<Item = (String, DeserializeWithRegistry<Box<dyn ServiceBuilder<Output = T>>>)>,

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.
