16/// The check flags user-defined move constructors and assignment operators not
17/// marked with `noexcept` or marked with `noexcept(expr)` where `expr`
18/// evaluates to `false` (but is not a `false` literal itself).
19///
20/// Move constructors of all the types used with STL containers, for example,
21/// need to be declared `noexcept`. Otherwise STL will choose copy constructors
22/// instead. The same is valid for move assignment operations.

void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
