Struct Source 

pub struct Source(pub Arc<str>);

The source the input ranges refer to.

Formats can publish the byte range in the input of every event (see State::input_range). This is cheap, but resolving the ranges into lines and columns (see Position::of) requires the source. As this requires a copy of the input, formats only provide it when asked to (for instance with their track_locations option). They store it in the State as an extension value with set before they emit the first event:

use deser::de::DeserializeDriver;
use deser::Source;

let mut out = None::<bool>;
let mut driver = DeserializeDriver::new(&mut out);
Source::set(driver.state_mut(), "true");
assert_eq!(&*driver.state().get::<Source>().unwrap().0, "true");
