Cargo Features

[dependencies]
unstructured = { version = "0.5.1", default-features = false, features = ["selector"] }
default = selector

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

selector default = pest, pest_derive

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.
