Cargo Features

[dependencies]
rainbow-core = { version = "0.1.0", default-features = false, features = ["html"] }
default = html

The html feature is set by default whenever rainbow-core is added without default-features = false somewhere in the dependency tree.

html default = html_parser

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.
