This project follows the AMQP 0.9.1 specifications, targeting especially RabbitMQ.

Feature switches

• native-tls (default): enable amqps support through native-tls
• openssl: enable amqps support through openssl (preferred over native-tls when set)
• rustls: enable amqps support through rustls (preferred over openssl when set, uses rustls-native-certs by default)
• rustls-native-certs: same as rustls, be ensure we'll still use rustls-native-certs even if the default for rustls changes
• rustls-webpki-roots-certs: same as rustls but using webkit-roots instead of rustls-native-certs
