Cargo Features

valuable = { version = "0.1.0", default-features = false, features = ["derive", "std", "alloc"] }
default = std

The std feature is set by default whenever valuable is added without default-features = false somewhere in the dependency tree.

derive = valuable-derive

Provide derive(Valuable) macro

std default = alloc

Provide impls for common standard library types like Vec<T> and HashMap<K, V>.

alloc std

Provide imps for types in Rust's alloc library.

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.

valuable-derive derive?
