Function to_string_with_options 

pub fn to_string_with_options<T: Facet<'static>>(
    value: &T,
    options: &SerializeOptions,
) -> Result<String, XmlError>

Serialize a value of type T to an XML string with custom options.

Example

#[derive(Facet)]
struct Person {
    #[facet(xml::attribute)]
    id: u32,
    #[facet(xml::element)]
    name: String,
}

let person = Person { id: 42, name: "Alice".into() };

// Compact output
let xml = to_string_with_options(&person, &SerializeOptions::default())?;
assert_eq!(xml, r#"<Person id="42"><name>Alice</name></Person>"#);

// Pretty output with tabs
let xml = to_string_with_options(&person, &SerializeOptions::default().indent("\t"))?;
