Cargo Features

BufStream has no features set by default.

[dependencies]
buf_stream = { version = "0.2.0", features = ["tokio"] }
tokio = futures, tokio-io

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.
