Cargo Features

[dependencies]
eff = { version = "0.1.0", default-features = false, features = ["futures-compat"] }
default = futures-compat

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

futures-compat default = futures

Affects eff::futures_compat, eff::Effectful.into_future

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.
