Cargo Features

[dependencies]
ethpm = { version = "0.1.0-alpha.3", default-features = false, features = ["std", "no-std"] }
default = serde, serde_json

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

std = serde, serde_json

enable support for the standard library

no-std = serde-json-core

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.
