Cargo Features

[dependencies]
async-foundation = { version = "0.2.1", default-features = false, features = ["test_tools", "net"] }
default = net

The net feature is set by default whenever async-foundation is added without default-features = false somewhere in the dependency tree.

test_tools
net default = mio

Enables net and os-poll of mio

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.
