Cargo Features

async-tls = { version = "0.12.0", default-features = false, features = ["client", "early-data", "server"] }
default = client, server

These default features are set whenever async-tls is added without default-features = false somewhere in the dependency tree.

client default = webpki, webpki-roots

Affects async-tls::client

server default

Affects async-tls::server

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features.
