Cargo Features

[dependencies]
psf2 = { version = "0.4.0", default-features = false, features = ["std", "unicode"] }
default = std, unicode

These default features are set whenever psf2 is added without default-features = false somewhere in the dependency tree.

std default
unicode default = hashbrown, rustc-hash

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.
