Cargo Features

[dependencies]
cov = { version = "0.0.5", default-features = false, features = ["serde", "serde_json"] }
default = serde, serde_json

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

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.

Affects intern::WithInterner, intern::SerializeWithInterner, cov::deserializer
