Crate yash_env 

This crate defines the shell execution environment.

A shell execution environment, Env, is a collection of data that may affect or be affected by the execution of commands. The environment consists of application-managed parts and system-managed parts. Application-managed parts are implemented in pure Rust in this crate. Many application-managed parts like functions and variables can be manipulated independently of interactions with the underlying system. System-managed parts, on the other hand, depend on the underlying system. Attributes like the working directory and umask are managed by the system to be accessed only by interaction with the system interface.

Traits declared in the system module define the interface to the system-managed parts of the environment. RealSystem provides an implementation for them that interacts with the underlying system. VirtualSystem simulates a system for testing purposes.
