Struct workdir::dirswitch::DirSwitch

pub struct DirSwitch { /* private fields */ }

RIIA directory change object.

Creating an instance of this object represents storing the current directory and then switching to the requested directory. Dropping it causes the directory to be switched back to the original directory.

Notes

There’s no ergonomic way to return errors from Drop handlers. If it is unable switch back to the original directory, this will be lost to the application, although an error will be printed on stderr.
