// serde = { version = "1.0", features = [ "derive" ] }
// quick-xml = { version = "0.21", features = [ "serialize" ] }
extern crate serde;
extern crate quick_xml;

Structs
An xml deserializer
Enums
(De)serialization error
Traits
A trait that borrows an XML reader that borrows from the input. For a &u8 input the events will borrow from that input, whereas with a BufRead input all events will be converted to ’static, allocating whenever necessary.
Functions
Deserialize a xml slice of bytes
Deserialize from a reader
Deserialize an instance of type T from bytes of XML text.
Deserialize an instance of type T from a string of XML text.
