Definition for a Component registered in a definition registry.

Fields

names: FxHashSet<String>

Each component has at least one name, which can be used to request a specific instance. Derive-based components have their name generated from type name by converting it to snake case.

is_primary: bool

With multiple components registered for a given type, one of them can be marked as primary and returned when requesting a single instance.

scope: String

Which type of Scope to use when requesting given component. Please see scope for details on scopes.

resolved_type_id: TypeId

Concrete component type id. Since aliases can share definitions with their targets, there can be a need to find out what is the leaf type.

resolved_type_name: String

Human-readable type name for reporting purposes.

constructor: Constructor

Constructor method for type-erased instances.

cast: CastFunction

Cast function associated for given type. Please see the documentation for CastFunction for details on usage.
