Cargo Features

[dependencies]
tenjin = { version = "0.5.1", default-features = false, features = ["serde_json", "toml"] }
default = serde_json, toml

These default features are set whenever tenjin 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.
