Constructor & Destructor Documentation

FormField()

template<PropertyValue T>

aria::binding::FormField< T >::FormField ( std::string field_path, T initial = T{} )

inlineexplicit

Construct from (field_path, initial).

The path flows into the owned Validator so every emitted Error is keyed by it.
