Cargo Features

[dependencies]
ppl = { version = "0.1.5", default-features = false, features = ["flume", "crossbeam", "ff", "kanal"] }
default = crossbeam

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

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.
