Cargo Features

[dependencies]
fruit-salad = { version = "0.0.2", default-features = false, features = ["std", "alloc", "macros"] }
default = std

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

std default = alloc
alloc std
macros = fruit-salad_proc-macro-definitions, static_assertions

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.

fruit-salad_proc-macro-definitions macros?
static_assertions macros?
