6//! # Cargo features
7//!
8//! ## TLS backends
9//!
10//! - `aws_lc_rs` (default) enables rustls with the `aws_lc_rs` backend.
11//! - `ring` enables rustls with the `ring` backend`.
12//! - `rustls-any-backend` enables rustls, but without enabling a backend. It
13//! is the application's responsibility to ensure that a backend is enabled
14//! and installed.
15//! - `ktls` enables the use of ktls.
16//! **Important:** Currently, connections will fail if the `tls` kernel
17//! module is not available. There is no fallback to non-ktls connections!
18//! - `native-tls` enables the system-native TLS library (commonly
19//! libssl/OpenSSL).
20//!
21//! **Note:** It is not allowed to mix rustls-based TLS backends with
22//! `tls-native`. Attempting to do so will result in a compilation error.
23//!
24//! **Note:** The `ktls` feature requires at least one `rustls` backend to be
25//! enabled (`aws_lc_rs` or `ring`).
26//!
27//! **Note:** When enabling not exactly one rustls backend, it is the
28//! application's responsibility to make sure that a default crypto provider is
29//! installed in `rustls`. Otherwise, all TLS connections will fail.
30//!
31//! ## Certificate validation
32//!
33//! When using `native-tls`, the system's native certificate store is used.
34//! Otherwise, you need to pick one of the following to ensure that TLS
35//! connections will succeed:
36//!
37//! - `rustls-native-certs` (default): Uses [rustls-native-certs](https://crates.io/crates/rustls-native-certs).
38//! - `webpki-roots`: Uses [webpki-roots](https://crates.io/crates/webpki-roots).
39//!
40//! ## Other features
41//!
42//! - `starttls` (default): Enables support for `<starttls/>`. Required as per
43//! RFC 6120.
44//! - `avatars` (default): Enables support for avatars.
45//! - `serde`: Enable the `serde` feature in `tokio-xmpp`.
