Cargo Features

classicube-sys has no features set by default.

[dependencies]
classicube-sys = { version = "4.0.0+classicube.1.3.7", features = ["no_std"] }
no_std = cstr_core, libc, libm

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.

cstr_core no_std?
libc no_std?
libm no_std?
