fn format() -> &'static str { ... } }

A trait that describes a type that can serialize a stream of values into the underlying format.

Associated Types

The error type that can be returned if some error occurs during serialization.

Required Methods

visit_bool serializes a bool value.

visit_i64 serializes a i64 value.

visit_u64 serializes a u64 value.

visit_f64 serializes a f64 value.

visit_str serializes a &str.

Serializes a () value.

Serializes a None value.

Serializes a Some(...) value.

Serializes a sequence.

Callees of this method need to construct a SeqVisitor, which iterates through each item in the sequence.

Serializes a sequence element.

Serializes a map.

Callees of this method need to construct a MapVisitor, which iterates through each item in the map.

Serializes a map element (key-value pair).

Provided Methods

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

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

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

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

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

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

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

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

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

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

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.

Serializes a unit struct value.

By default, unit structs are serialized as a ().

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

By default, unit variants are serialized as a ().

The visit_newtype_struct allows a tuple struct with a single element, also known as a newtyped value, to be more efficiently serialized than a tuple struct with multiple items. By default it just serializes the value as a tuple struct sequence.

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.

Serializes a tuple.

By default this serializes a tuple as a sequence.

Serializes a tuple element.

By default, tuples are serialized as a sequence.

Serializes a tuple struct.

By default, tuple structs are serialized as a tuple.

Serializes a tuple struct element.

By default, tuple struct elements are serialized as a tuple element.

Serializes a tuple variant.

By default, tuple variants are serialized as a tuple struct.

Serializes a tuple element.

By default, tuples are serialized as a sequence.

Serializes a struct.

By default, structs are serialized as a map with the field name as the key.

Serializes an element of a struct.

By default, struct elements are serialized as a map element with the field name as the key.

Serializes a struct variant.

By default, struct variants are serialized as a struct.

Serializes an element of a struct variant.

By default, struct variant elements are serialized as a struct element.

Specify a format string for the serializer.

The serializer format is used to determine which format specific field attributes should be used with the serializer.
