Cargo Features

[dependencies]
asak = { version = "0.3.3", default-features = false, features = ["jack"] }
default = cpal

The cpal feature is set by default whenever asak 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.
