Requires a dependency on the Rust standard library.

serde std

Serde support without relying on std features.

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.
