Struct home::env::OsEnv

pub struct OsEnv;

Implements Env for the OS context, both Unix style and Windows.

This is trait permits in-process testing by providing a control point to allow in-process divergence on what is normally process wide state.

Implementations should be provided by whatever testing framework the caller is using. Code that is not performing in-process threaded testing requiring isolated rustup/cargo directories does not need this trait or the _from functions.
