Cargo Features

[dependencies]
compiler-tools = { version = "0.2.0", default-features = false, features = ["use_regex", "serde"] }
default = serde, use_regex

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

use_regex default = regex

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.
