fn visit_unit_variant(

The visit_newtype_variant allows a variant with a single item to be more efficiently serialized than a variant with multiple items. By default it just serializes the value as a tuple variant sequence.

    V: SeqVisitor, 

Serializes a tuple variant.

fn visit_seq_elt<T>(&mut self, value: T) -> Result<(), ()> where
    T: Serialize,

    V: MapVisitor, 

Serializes a map.

fn visit_struct_variant<V>(
    &mut self,
    _name: &str,
    _variant_index: usize,
    variant: &str,
    visitor: V
) -> Result<(), ()> where
    V: MapVisitor, 

Serializes a struct variant.

fn visit_map_elt<K, V>(&mut self, key: K, value: V) -> Result<(), ()> where
    K: Serialize,
    V: Serialize, 

Serializes a map element (key-value pair).

fn format() -> &'static str

Specify a format string for the serializer.

fn visit_isize(&mut self, v: isize) -> Result<(), Self::Error>

visit_isize serializes a isize value. By default it casts the value to a i64 and passes it to the visit_i64 method.

fn visit_i8(&mut self, v: i8) -> Result<(), Self::Error>

visit_i8 serializes a i8 value. By default it casts the value to a i64 and passes it to the visit_i64 method.

fn visit_i16(&mut self, v: i16) -> Result<(), Self::Error>

visit_i16 serializes a i16 value. By default it casts the value to a i64 and passes it to the visit_i64 method.

fn visit_i32(&mut self, v: i32) -> Result<(), Self::Error>

visit_i32 serializes a i32 value. By default it casts the value to a i64 and passes it to the visit_i64 method.

fn visit_usize(&mut self, v: usize) -> Result<(), Self::Error>

visit_usize serializes a usize value. By default it casts the value to a u64 and passes it to the visit_u64 method.

fn visit_u16(&mut self, v: u16) -> Result<(), Self::Error>

visit_u32 serializes a u32 value. By default it casts the value to a u64 and passes it to the visit_u64 method.

fn visit_u32(&mut self, v: u32) -> Result<(), Self::Error>

visit_u32 serializes a u32 value. By default it casts the value to a u64 and passes it to the visit_u64 method.

fn visit_f32(&mut self, v: f32) -> Result<(), Self::Error>

visit_f32 serializes a f32 value. By default it casts the value to a f64 and passes it to the visit_f64 method.

fn visit_bytes(&mut self, value: &[u8]) -> Result<(), Self::Error>

visit_bytes is a hook that enables those serialization formats that support serializing byte slices separately from generic arrays. By default it serializes as a regular array.

fn visit_unit_struct(&mut self, _name: &'static str) -> Result<(), Self::Error>
