Cargo Features

[dependencies]
librum = { version = "0.13.0", default-features = false, features = ["std", "alloc", "proc-macro"] }
default = alloc, proc-macro, std

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

std default
alloc default
proc-macro default = librum-macros

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.
