Cargo Features

[dependencies]
scoped-callback = { version = "0.2.0", default-features = false, features = ["std", "async"] }
default = async, std

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

std default
async default = futures-util

Affects scoped-callback::scope_async, scoped-callback::scope_async_local

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.
