Cargo Features

dhall = { version = "0.12.0", default-features = false, features = ["reqwest"] }
default = reqwest

The reqwest feature is set by default whenever dhall 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.
