Expand description
Provides a ProductVisitor
with access to each element of the named product in the input.
This is a trait that a Deserializer
passes to a ProductVisitor
implementation.

Required Methods§
sourcefn get_field_ident<V: FieldNameVisitor<'de>>(
&mut self,
visitor: V
) -> Result<Option<V::Output>, Self::Error>
fn get_field_ident<V: FieldNameVisitor<'de>>( &mut self, visitor: V ) -> Result<Option<V::Output>, Self::Error>
Deserializes field name of type V::Output
from the input using a visitor
provided by the deserializer.
sourcefn get_field_value_seed<T: DeserializeSeed<'de>>(
&mut self,
seed: T
) -> Result<T::Output, Self::Error>
fn get_field_value_seed<T: DeserializeSeed<'de>>( &mut self, seed: T ) -> Result<T::Output, Self::Error>
Statefully deserializes the field value T::Output
from the input provided a seed
value.
Deserialize
implementations should typically use
next_element
instead.
Provided Methods§
sourcefn get_field_value<T: Deserialize<'de>>(&mut self) -> Result<T, Self::Error>
fn get_field_value<T: Deserialize<'de>>(&mut self) -> Result<T, Self::Error>
Deserializes field value of type T
from the input.
This method exists as a convenience for Deserialize
implementations.
NamedProductAccess
implementations should not override the default behavior.
Object Safety§
This trait is not object safe.
