Structs

Args	An iterator over the arguments of a process, yielding a String value for each argument.
ArgsOs	An iterator over the arguments of a process, yielding an OsString value for each argument.
JoinPathsError	Error type returned from std::env::join_paths when paths fail to be joined.
SplitPaths	An iterator over Path instances for parsing an environment variable according to platform-specific conventions.
Vars	An iterator over a snapshot of the environment variables of this process.
VarsOs	An iterator over a snapshot of the environment variables of this process.

Enums

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 Path.
current_exe	Optionally returns the filesystem path to the current executable which is running but with the executable name.
get_exit_status	Fetches the process's current exit code. This defaults to 0 and can change by calling set_exit_status.
home_dir	Optionally returns the path to the current user's home directory if known.
join_paths	Joins a collection of Paths appropriately for the PATH environment variable.
page_size	Returns the page size of the current architecture in bytes.
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_exit_status	Sets the process exit code
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.
