Cargo Features

[dependencies]
osauth = { version = "0.5.0", default-features = false, features = ["default-rustls", "native-tls", "rustls", "stream"] }
default = native-tls, stream

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

default-rustls = rustls, stream
native-tls default

Enables default-tls of reqwest

reqwest:

Note: this doesn't enable the 'native-tls' feature, which adds specific functionality for it.

rustls default-rustls?

Enables rustls-tls of reqwest

stream default default-rustls? = async-stream, futures

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.
