1.0.0[−][src]Module std::env
Inspection and manipulation of the process's environment.
This module contains functions to inspect various aspects such as environment variables, process arguments, the current directory, and various other important directories.
There are several functions and structs in this module that have a
counterpart ending in os
. Those ending in os
will return an OsString
and those without will be returning a String
.
