Function tracing::stdlib::env::args

pub fn args() -> Args 

Returns the arguments that 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 might not even exist. This means this property should not be relied upon for security purposes.

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

On glibc Linux systems, arguments are retrieved by placing a function in .init_array. glibc passes argc, argv, and envp to functions in .init_array, as a non-standard extension. This allows std::env::args to work even in a cdylib or staticlib, as it does on macOS and Windows.

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}");
}
