}Expand description
This trait represents a visitor is “driven” by the deserializer to construct an instance of your type.
Required Associated Types§
sourcetype ArrayElem
type ArrayElem
The element type Visitor::visit_array is expecting as input.
Only used for visitors implementing this method,
std::convert::Infallible can be used as a default.
