Function from_reader 

pub fn from_reader<T: FromXml, R: BufRead>(r: R) -> Result<T>

Available on crate feature std only.

Parse a value from a io::BufRead

This function parses the XML found in r, assuming it contains a complete XML document (with optional XML declaration) and builds a T from it (without buffering the tree in memory).

If conversion fails, a Error is returned. In particular, if T expects a different element header than the element header at the root of the document in r, Error::TypeMismatch is returned.

Example

#[derive(FromXml, PartialEq, Debug)]
#[xml(namespace = "urn:example", name = "foo")]
struct Foo {
    #[xml(attribute)]
    a: String,
}

// let file = ..
assert_eq!(
    Foo { a: "some-value".to_owned() },
    from_reader(BufReader::new(file)).unwrap(),
);
