Cargo Features

[dependencies]
one-of-futures = { version = "0.1.4", default-features = false, features = ["sink", "futures_03", "futures_01", "tokio-io"] }
default = sink

The sink feature is set by default whenever one-of-futures is added without default-features = false somewhere in the dependency tree.

sink default = futures-sink, futures_03
futures_03 sink = futures-core
futures_01 = futures-01

Affects one-of-futures::futures_01

tokio-io = tokio
