Cargo Features

[dependencies]
doubter-macros = { version = "0.1.0", default-features = false, features = ["proc-macro-hack"] }

default = proc-macro-hack

The proc-macro-hack feature is set by default whenever doubter-macros is added without default-features = false somewhere in the dependency tree.

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).
