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_u8(&mut self, value: u8) -> Result<()>

visit_u8 serializes a u8 value. By default it casts the value to a u64 and passes it to the visit_u64 method.

fn visit_u16(&mut self, value: u16) -> Result<()>

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, value: u32) -> Result<()>

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_u64(&mut self, value: u64) -> Result<()>

visit_u64 serializes a u64 value.

fn visit_f32(&mut self, value: f32) -> Result<()>

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_f64(&mut self, value: f64) -> Result<()>

visit_f64 serializes a f64 value.

fn visit_char(&mut self, value: char) -> Result<()>

visit_char serializes a character. By default it serializes it as a &str containing a single character.

fn visit_str(&mut self, value: &str) -> Result<()>

visit_str serializes a &str.

fn visit_none(&mut self) -> Result<()>

Serializes a None value.

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

Serializes a Some(...) value.

fn visit_unit(&mut self) -> Result<()>

Serializes a () value.

fn visit_newtype_struct<T>(
    &mut self,
    _name: &'static str,
    value: T
) -> Result<()> where
    T: Serialize, 

Override visit_newtype_struct to serialize newtypes without an object wrapper.

fn visit_unit_variant(
    &mut self,
    _name: &str,
    _variant_index: usize,
    variant: &str
) -> Result<()>

Serializes a unit variant, otherwise known as a variant with no arguments.

fn visit_newtype_variant<T>(
    &mut self,
    _name: &str,
    _variant_index: usize,
    variant: &str,

) -> Result<()> where
    T: Serialize, 

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.

fn visit_seq<V>(&mut self, visitor: V) -> Result<()> where
    V: SeqVisitor, 

Serializes a sequence.

fn visit_tuple_variant<V>(
    &mut self,

Serializes a tuple variant.

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

Serializes a sequence element.

    V: MapVisitor, 

Serializes a map.

fn visit_struct_variant<V>(
    &mut self,
    _name: &str,
    _variant_index: usize,
    variant: &str,
    visitor: V

    V: MapVisitor, 

Serializes a struct variant.

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

Specify a format string for the serializer.

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.
