Cargo Features

[dependencies]
rbdc = { version = "4.5.45", default-features = false, features = ["tls-rustls", "tls-native-tls"] }
default = tls-rustls

The tls-rustls feature is set by default whenever rbdc is added without default-features = false somewhere in the dependency tree.

tls-rustls default = rustls, rustls-pemfile, tokio-rustls, webpki-roots
tls-native-tls = native-tls, tokio-native-tls

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

tokio-rustls tls-rustls
rustls tls-rustls
webpki-roots tls-rustls
rustls-pemfile tls-rustls
tokio-native-tls tls-native-tls?
native-tls tls-native-tls?
