Cargo Features

[dependencies]
maybe-unwind = { version = "0.3.1", default-features = false, features = ["futures"] }

default = futures

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

futures default = futures-core

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.
