Crate current

Current

A library for setting current values for stack scope, such as application structure

Current objects are put on a shadow stack for easy access by type. The type is used as an identifier to get the latest current object in scope.

This is used as a better alternative in Rust than mutable globals.

There are two objects in this library:

• CurrentGuard is used to create a current object using a mutable reference
• Current is used to access the reference by type

How to use it
