Cargo Features
Kern has no features set by default.
[dependencies]
kern = { version = "1.7.1", features = ["tls"] }- tls = rustls, rustls-pemfile, rustls-pki-types
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.
