Cargo Features

[dependencies]
dequemap = { version = "0.2.1", default-features = false, features = ["std", "btreemap", "hashmap", "serde"] }
default = btreemap, std

These default features are set whenever dequemap 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.

A generic serialization/deserialization framework
