Cargo Features

[dependencies]
futures-spawn = { version = "0.1.1", default-features = false, features = ["use_std", "tokio"] }

default = tokio, use_std

These default features are set whenever futures-spawn is added without default-features = false somewhere in the dependency tree.

use_std default

Enables use_std of futures ^0.1

tokio default = tokio-core

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](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).
