Cargo Features

propfuzz = { version = "0.0.1", default-features = false, features = ["macro"] }
default = macro

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

macro default = propfuzz-macro

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.
