fn deserialize_char<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a char value.

fn deserialize_str<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a &str value.

fn deserialize_string<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a String value.

fn deserialize_unit<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting an unit value.

fn deserialize_seq<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a sequence value. This allows deserializers to parse sequences that aren't tagged as sequences.

fn deserialize_fixed_size_array<V>(&mut self, _len: usize, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a fixed size array. This allows deserializers to parse arrays that aren't tagged as arrays.

fn deserialize_bytes<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a Vec<u8>. This allows deserializers that provide a custom byte vector serialization to properly deserialize the type.

fn deserialize_map<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a map of values. This allows deserializers to parse sequences that aren't tagged as maps.

fn deserialize_unit_struct<V>(&mut self, _name: &'static str, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a unit struct. This allows deserializers to a unit struct that aren't tagged as a unit struct.

fn deserialize_tuple_struct<V>(&mut self, _name: &'static str, len: usize, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a tuple struct. This allows deserializers to parse sequences that aren't tagged as sequences.

fn deserialize_struct<V>(&mut self, _name: &'static str, _fields: &'static [&'static str], visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

fn deserialize_struct_field<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting some sort of struct field name. This allows deserializers to choose between &str, usize, or &[u8] to properly deserialize a struct field.

fn deserialize_tuple<V>(&mut self, _len: usize, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a tuple value. This allows deserializers that provide a custom tuple serialization to properly deserialize the type.

fn deserialize_ignored_any<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type needs to deserialize a value whose type doesn't matter because it is ignored.
