Cargo Features

TypeLayout has no features set by default.

[dependencies]
type-layout = { version = "0.2.0", features = ["serde1"] }
serde1 = 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.
