Deserializer is a trait that can deserialize values by threading a Visitor trait through a value. It supports two entry point styles which enables different kinds of deserialization.

Associated Types

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

Required Methods

This method walks a visitor through a value as it is being deserialized.

Provided Methods

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

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

This method hints that the Deserialize type is expecting an u8 value.

This method hints that the Deserialize type is expecting an u16 value.

This method hints that the Deserialize type is expecting an u32 value.

This method hints that the Deserialize type is expecting an u64 value.

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

This method hints that the Deserialize type is expecting an i8 value.

This method hints that the Deserialize type is expecting an i16 value.

This method hints that the Deserialize type is expecting an i32 value.

This method hints that the Deserialize type is expecting an i64 value.

This method hints that the Deserialize type is expecting a f32 value.

This method hints that the Deserialize type is expecting a f64 value.

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

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

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

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

This method hints that the Deserialize type is expecting an Option value. This allows deserializers that encode an optional value as a nullable value to convert the null value into a None, and a regular value as Some(value).

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

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.

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.

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

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

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

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.

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

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.

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

Specify a format string for the deserializer.

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