Cargo Features

[dependencies]
good_memory_allocator = { version = "0.1.7", default-features = false, features = ["allocator"] }
default = spin

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

allocator = spin

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.
