+Disabling and suppressing
+-------------------------
-In some circumstances, you may want to suppress error reporting in a specific
scope.
+There are multiple ways to suppress error reporting when using
RealtimeSanitizer.
-In C++, this is achieved via ``__rtsan::ScopedDisabler``. Within the scope
where the ``ScopedDisabler`` object is instantiated, all sanitizer error
reports are suppressed. This suppression applies to the current scope as well
as all invoked functions, including any functions called transitively.
+In general, ``ScopedDisabler`` should be preferred, as it is the most
performant.

I would also not add too many implementation details into the public
documentation. It's unlikely to be useful, not unlikely to be wrong at some
point in the future when the implementation changes.
