Cargo Features

[dependencies]
no-proxy = { version = "0.3.5", default-features = false, features = ["serialize", "graphql"] }
default = serialize

The serialize feature is set by default whenever no-proxy is added without default-features = false somewhere in the dependency tree.

serialize default = serde
graphql = async-graphql

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.
