Cargo Features

[dependencies]
futurify = { version = "0.3.0", default-features = false, features = ["futures_01", "futures_03"] }

default = futures_03

The futures_03 feature is set by default whenever futurify is added without default-features = false somewhere in the dependency tree.

futures_01 = futures01

futures_03 default = futures03
