Cargo Features

simi-macros = { version = "0.2.1", default-features = false, features = ["nightly", "proc-macro-hack"] }
default = proc-macro-hack

The proc-macro-hack feature is set by default whenever simi-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.
