Cargo Features

Fuse-Rust has no features set by default.

[dependencies]
fuse-rust = { version = "0.3.2", features = ["async"] }
async = crossbeam-utils

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.
