This project follows the AMQP 0.9.1 specifications, targeting especially RabbitMQ.
codegen
: generate code instead of using pregenerated onenative-tls
(default): enable amqps support through native-tlsopenssl
: 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 changesrustls-webpki-roots-certs
: same as rustls but using webkit-roots instead of rustls-native-certs
