18/// Macro for printing to the trace output, without a newline.
19///
20/// Equivalent to the `trace_println!` macro expect that a newline is not
21/// printed at the end of the message.
22///
23/// # Examples
24///
25/// ``` rust,no_run
26/// # use optee_utee::trace_print;
27///
28/// trace_print!("this ");
29/// trace_print!("will ");
30/// trace_print!("be ");
31/// trace_print!("on ");
32/// trace_print!("the ");
33/// trace_print!("same ");
34/// trace_print!("line ");
35/// trace_print!("this string has a newline, why not choose println! instead?\n");
36/// ```
37#[macro_export]
38macro_rules! trace_print {
39    ($($arg:tt)*) => ($crate::trace::Trace::_print(format_args!($($arg)*)));

42/// Macro for printing to the trace output, with a newline.
43/// Use the `format!` syntax to write data to the standard output. See
