### Important traits for Args

`impl Iterator for Args type Item = String;`

    pub fn args() -> Args

Returns the arguments which this program was started with (normally passed via the command line).

The first element is traditionally the path of the executable, but it can be set to arbitrary text, and may not even exist. This means this property should not be relied upon for security purposes.

On Unix systems shell usually expands unquoted arguments with glob patterns (such as `*` and `?`). On Windows this is not done, and such arguments are passed as-is.

# Panics

The returned iterator will panic during iteration if any argument to the process is not valid unicode. If this is not desired, use the `args_os` function instead.

# Examples

    use std::env;

    // Prints each argument on a separate line
    for argument in env::args() {
        println!("{}", argument);
    }Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
