Cargo Features

[dependencies]
merge = { version = "0.1.0", default-features = false, features = ["std", "derive", "num"] }
default = derive, num, std

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

std default

Affects merge::vec

derive default = merge_derive
num default = num-traits

Affects merge::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.
