Expand description

A trait providing a representation of a resolved component instance.

Required Associated Types§

Source

type Component

Type representing a (unlocked and potentially unresolved) component instance.

Required Methods§

Source

fn try_uses(&self) -> Option<Box<[UseDecl]>>

Current view of this component’s uses declarations. Implementers are not required to retain their component declaration and in that case should return None.

Source

fn try_exposes(&self) -> Option<Box<[ExposeDecl]>>

Current view of this component’s exposes declarations. Implementers are not required to retain their component declaration and in that case should return None.

Source

fn try_offers(&self) -> Option<Box<[OfferDecl]>>

Current view of this component’s offers declarations. Does not include any dynamic offers between children of this component. Implementers are not required to retain their component declaration and in that case should return None.

Source

fn try_capabilities(&self) -> Option<Box<[CapabilityDecl]>>

Current view of this component’s capabilities declarations. Implementers are not required to retain their component declaration and in that case should return None.

Source

fn try_collections(&self) -> Option<Box<[CollectionDecl]>>

Current view of this component’s collections declarations. Implementers are not required to retain their component declaration and in that case should return None.

Source

fn get_child(&self, moniker: &BorrowedChildName) -> Option<Arc<Self::Component>>

Returns a live child of this instance.

Source

fn children_in_collection( &self, collection: &Name, ) -> Vec<(ChildName, Arc<Self::Component>)>

Returns a vector of the live children in collection.

Source

fn address<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<ComponentAddress, ResolverError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the resolver-ready location of the component, which is either an absolute component URL or a relative path URL with context.

Source

fn context_to_resolve_children(&self) -> Option<ComponentResolutionContext>

Returns the context to be used to resolve a component from a path relative to this component (for example, a component in a subpackage). If None, the resolver cannot resolve relative path component URLs.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
