Macro processing::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);
