VarError

Possible errors from the env::var method.

Functions

args	Returns the arguments which this program was started with (normally passed via the command line).
args_os	Returns the arguments which this program was started with (normally passed via the command line).
current_dir	Returns the current working directory as a `PathBuf`.
current_exe	Returns the filesystem path to the current executable which is running but with the executable name.
home_dir	Returns the path to the current user's home directory if known.
join_paths	Joins a collection of `Path`s appropriately for the `PATH` environment variable.
remove_var	Removes an environment variable from the environment of the currently running process.
set_current_dir	Changes the current working directory to the specified path, returning whether the change was completed successfully or not.
set_var	Sets the environment variable `k` to the value `v` for the currently running process.
split_paths	Parses input according to platform conventions for the `PATH` environment variable.
temp_dir	Returns the path to a temporary directory.
var	Fetches the environment variable `key` from the current process.
var_os	Fetches the environment variable `key` from the current process, returning None if the variable isn't set.
vars	Returns an iterator of (variable, value) pairs of strings, for all the environment variables of the current process.
vars_os	Returns an iterator of (variable, value) pairs of OS strings, for all the environment variables of the current process.
