## Enables support for asynchronous reading from `tokio`'s IO-Traits by enabling
## [reading events] from types implementing [`tokio::io::AsyncBufRead`].
##
## [reading events]: crate::reader::Reader::read_event_into_async
async-tokio = ["tokio"]

## Enables support of non-UTF-8 encoded documents. Encoding will be inferred from
## the XML declaration if it will be found, otherwise UTF-8 is assumed.
##
## Currently, only ASCII-compatible encodings are supported, so, for example,
## UTF-16 will not work (therefore, `quick-xml` is not [standard compliant]).
##
## Thus, quick-xml supports all encodings of [`encoding_rs`] except these:
## - [UTF-16BE]
## - [UTF-16LE]
## - [ISO-2022-JP]
##
## You should stop to process document when one of that encoding will be detected,
## because generated events can be wrong and do not reflect a real document structure!
##
## Because there is only supported encodings that is not ASCII compatible, you can
## check for that to detect them:
##
## ```
## use quick_xml::events::Event;
## use quick_xml::reader::Reader;
##
## # fn to_utf16le_with_bom(string: &str) -> Vec<u8> {
## #     let mut bytes = Vec::new();
## #     bytes.extend_from_slice(&[0xFF, 0xFE]); // UTF-16 LE BOM
## #     for ch in string.encode_utf16() {
## #         bytes.extend_from_slice(&ch.to_le_bytes());
## #     }
## #     bytes
## # }
## let xml = to_utf16le_with_bom(r#"<?xml encoding='UTF-16'><element/>"#);
## let mut reader = Reader::from_reader(xml.as_ref());
## reader.trim_text(true);
##
## let mut buf = Vec::new();
## let mut unsupported = false;
## loop {
##     if !reader.decoder().encoding().is_ascii_compatible() {
##         unsupported = true;
##         break;
##     }
##     buf.clear();
##     match reader.read_event_into(&mut buf).unwrap() {
##         Event::Eof => break,
##         _ => {}
##     }
## }
## assert_eq!(unsupported, true);
## ```
## That restriction will be eliminated once issue [#158] is resolved.

## This feature for a serde deserializer that enables support for deserializing
## lists where tags are overlapped with tags that do not correspond to the list.
##
## When this feature is enabled, the XML:
## ```xml
## <any-name>
##   <item/>
##   <another-item/>
##   <item/>
##   <item/>
## </any-name>
## ```
## could be deserialized to a struct:
## ```no_run
## # use serde::Deserialize;
## #[derive(Deserialize)]
## #[serde(rename_all = "kebab-case")]
## struct AnyName {
##   item: Vec<()>,
##   another_item: (),
## }
## ```
##
## When this feature is not enabled (default), only the first element will be
## associated with the field, and the deserialized type will report an error
## (duplicated field) when the deserializer encounters a second `<item/>`.
##
## Note, that enabling this feature can lead to high and even unlimited memory
## consumption, because deserializer should check all events up to the end of a
## container tag (`</any-name>` in that example) to figure out that there are no
## more items for a field. If `</any-name>` or even EOF is not encountered, the
## parsing will never end which can lead to a denial-of-service (DoS) scenario.
##
## Having several lists and overlapped elements for them in XML could also lead
## to quadratic parsing time, because the deserializer must check the list of
## events as many times as the number of sequence fields present in the schema.
##
## To reduce negative consequences, always [limit] the maximum number of events
## that [`Deserializer`] will buffer.
##
## This feature works only with `serialize` feature and has no effect if `serialize`
## is not enabled.
