Function v8::V8::set_flags_from_command_line_with_usage

pub fn set_flags_from_command_line_with_usage(
    args: Vec<String>, 
    usage: Option<&str>
) -> Vec<String>

The example code below is here to avoid the V8 usage string and options that are printed to stdout by this function. Placing this here instead of in a test allows the output to be suppressed.

Examples

    use rusty_v8 as v8;
    let r = v8::V8::set_flags_from_command_line_with_usage(
      vec!["binaryname".to_string(), "--help".to_string()],
      Some("Usage: binaryname --startup-src=file\n\n"),
    );
    assert_eq!(r, vec!["binaryname".to_string()]);
