pub struct RequiredComponent {
pub constructor: RequiredComponentConstructor,
pub inheritance_depth: u16,
}Expand description
Metadata associated with a required component. See Component for details.
Fields§
§constructor: RequiredComponentConstructorThe constructor used for the required component.
inheritance_depth: u16The depth of the component requirement in the requirement hierarchy for this component. This is used for determining which constructor is used in cases where there are duplicate requires.
For example, consider the inheritance tree X -> Y -> Z, where -> indicates a requirement.
X -> Y and Y -> Z are direct requirements with a depth of 0, while Z is only indirectly
required for X with a depth of 1.
In cases where there are multiple conflicting requirements with the same depth, a higher priority
will be given to components listed earlier in the require attribute, or to the latest added requirement
if registered at runtime.
