Cargo Features

[dependencies]
karyon_async_rustls = { version = "0.1.6", default-features = false, features = ["smol", "tokio"] }
default = smol

The smol feature is set by default whenever karyon_async_rustls is added without default-features = false somewhere in the dependency tree.

smol default = futures-rustls
tokio = tokio-rustls

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.

futures-rustls smol
tokio-rustls tokio?
