Function libra_error_write 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn libra_error_write(
    error: libra_error_t,
    out: *mut MaybeUninit<*mut c_char>,
) -> i32

Writes the error message into out

If error is null, this function does nothing and returns 1. Otherwise, this function returns 0.

Safety

• error must be a valid and initialized instance of libra_error_t.
• out must be a non-null pointer. The resulting string must not be modified.
