Cargo Features

atom_syndication = { version = "0.12.3", default-features = false, features = ["builders", "with-serde"] }
default = builders

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

builders default = derive_builder, never
with-serde = serde

Enables serde of chrono

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.
