A no-std string splitter for which spaces between quotes aren't separators.

use splitty::*;

let cmd = "xterm -e \"vi /some/path\"";

let mut token = split_unquoted_char(cmd, ' ')
    .unwrap_quotes(true);

assert_eq!(token.next(), Some("xterm"));
assert_eq!(token.next(), Some("-e"));
assert_eq!(token.next(), Some("vi /some/path"));
assert_eq!(token.next(), None);

Quotes not starting or ending a substring are handled as ordinary characters.

Splitty has a limited set of features but is tested for corner-cases:

use splitty::*;

let cmd = r#" a  "2 * 试" x"x "z "#;

let mut token = split_unquoted_whitespace(cmd)
    .unwrap_quotes(true);

assert_eq!(token.next(), Some("a"));
assert_eq!(token.next(), Some("2 * 试"));
assert_eq!(token.next(), Some("x\"x"));
assert_eq!(token.next(), Some("\"z "));
assert_eq!(token.next(), None);
