Cargo Features

spirv_headers has no features set by default.

[dependencies]
spirv_headers = { version = "1.5.0", features = ["serialize", "deserialize"] }
serialize = serde
deserialize = serde

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.
