Macro glium::assert_no_gl_error

macro_rules! assert_no_gl_error {
    ($display: expr) => { ... };
    ($display: expr, $msg: expr) => { ... };
    ($display: expr, $fmt: expr, $($arg:tt)+) => { ... };
}

Calls the assert_no_error method on a glium::Display instance with file and line number information.

Aside from the first argument which must be the display, the arguments of this macro match the println! macro.

Example

assert_no_gl_error!(my_display);
assert_no_gl_error!(my_display, "custom message");
assert_no_gl_error!(my_display, "custom format {}", 5);
