[−][src]Module quick_xml::de

Serde Deserializer module
Examples

Here is a simple example parsing crates.io source code.
// Cargo.toml
// [dependencies]
// serde = { version = "1.0", features = [ "derive" ] }
// quick_xml = { version = "0.17", features = [ "serialize" ] }
extern crate serde;
extern crate quick_xml;

use serde::Deserialize;
use quick_xml::de::{from_str, DeError};
