Getting Carbon Fields value inside of namespace

Question

How can you access the carbon_get_post_meta function from within a namespace?

namespace SeoThemes\GenesisStarterTheme\Functions;

if ( function_exists( 'carbon_get_post_meta' ) ):
    echo 'true';
else:
    echo 'false';
endif;

This returns false currently, but if I do the same thing inside of page.php it returns true.

I know that I'll have to fix the namespace issue, I just don't know how... I thought if I add \ first then it'd go to the root namespace but it still returns false.

i.e. \carbon_get_post_meta

Can anyone help?
