Cargo Features

[dependencies]
pw-telegram-bot-fork = { version = "0.9.2", default-features = false, features = ["openssl", "rustls"] }
default = openssl

The openssl feature is set by default whenever pw-telegram-bot-fork is added without default-features = false somewhere in the dependency tree.

openssl default = hyper-tls
rustls = hyper-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.
