Cargo Features

Claude has no features set by default.

[dependencies]
claude = { version = "0.3.1", features = ["serialization", "parsing"] }
serialization = serde, serde_derive, serde_json
parsing = regex

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.

regex parsing?
serde serialization?
serde_json serialization?
serde_derive serialization?
