fn __fmt_eprint(s: &[u8]) -> void

Writes s to stderr; pub only so eprint! expansions resolve it.

Writes s and a newline to stderr; pub only so eprintln! expansions resolve it.

fn __fmt_panic(msg: &[u8]) -> !

Panics with msg; -> ! makes panic! expansions type as ! in expression position.

fn __fmt_print(s: &[u8]) -> void

Writes s to stdout; pub only so print! expansions resolve it.

fn __fmt_println(s: &[u8]) -> void

fn format_args_str(pat: &[u8], args: T) -> String

Formats args into a new String per the {}/{:?} placeholders in pat. Runtime fallback for dynamic (non-literal) patterns; handles only {} (Display), {:?} (Debug), and {{/}} escapes — no format-spec parsing.
