Struct RequiredComponent

pub struct RequiredComponent {
    pub constructor: RequiredComponentConstructor,
    pub inheritance_depth: u16,
}

Metadata associated with a required component. See Component for details.

Fields

constructor: RequiredComponentConstructor

The constructor used for the required component.

inheritance_depth: u16

The 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.
