Cargo Features

[dependencies]
merge2 = { version = "0.3.0", default-features = false, features = ["std", "derive", "num"] }
default = derive, std

These default features are set whenever merge2 is added without default-features = false somewhere in the dependency tree.

std default

Affects merge2::string, merge2::vec, merge2::hashmap

derive default = merge2_derive
num = num-traits

Affects merge2::num

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.

num-traits num?
