Function local_global 

pub fn local_global<T: Zeroable + Sync + 'static>() -> &'static T

Available on crate feature std or x86-64 or AArch64 or ARM or x86 only.

Like global, but the symbol identifying the storage will not be exported.

This means different binaries linked together may not share the same instance of this global variable, but the binary may be smaller (if many such globals are exposed).

Globals defined with global and local_global are separate from each other.
