Cargo Features

[dependencies]
promising-future = { version = "0.2.4", default-features = false, features = ["unstable", "threadpool"] }

default = threadpool

The threadpool feature is set by default whenever promising-future is added without default-features = false somewhere in the dependency tree.

unstable

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.
