itertools = { version = "0.12.1", default-features = false, features = ["use_std", "use_alloc"] }

default = use_std

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

use_std default = use_alloc

Enables use_std of either
