Cargo Features

[dependencies]
zc = { version = "0.4.0", default-features = false, features = ["std", "alloc", "derive"] }
default = derive, std

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

std default = alloc
alloc std = aliasable
derive default = zc-derive

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.

zc-derive derive
aliasable alloc?
