Cargo Features

merge-hashmap = { version = "0.1.2", default-features = false, features = ["std", "derive", "num"] }
default = derive, num, std

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

std default

Affects merge-hashmap::vec, merge-hashmap::hashmap

derive default = merge_derive-hashmap
num default = num-traits

Affects merge-hashmap::num

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features.
