Cargo Features

[dependencies]
fsevent-stream = { version = "0.2.3", default-features = false, features = ["tokio", "async-std"] }
default = tokio

The tokio feature is set by default whenever fsevent-stream is added without default-features = false somewhere in the dependency tree.

tokio default = tokio-stream, tokio1
async-std = async-std1

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.
