Cargo Features

treediff has no features set by default.

treediff = { version = "5.0.0", features = ["with-rustc-serialize", "with-serde-json", "with-serde-yaml", "with-yaml-rust"] }
with-rustc-serialize = rustc-serialize
with-serde-json = serde_json
with-serde-yaml = serde_yaml
with-yaml-rust = yaml-rust

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.
