struct tim::trait::collects_data< T >
trait that specifies or determines if a component collects any data. Default behavior is to check if the component is available and extract the type and value fields from tim::trait::component_value_type. When a component is available, the 'type' of this trait will return the 'value type' for a component regardless of whether it was specified within the component definition or if it was declared via a type-trait. The constexpr 'value' boolean indicates whether the 'type' is not a null type.
