	English ```c++ template<class ExecutionPolicy, class F> void erase_if(ExecutionPolicy&& policy, F f); ``` 98/10000 · 98
372 :1548

	English Invokes `f` with non-const references to each of the elements in the table, and erases those for which `f` returns `true`. Execution is parallelized according to the semantics of the execution policy specified. 210/10000 · 210
373 :1552

	English Throws:;; Depending on the exception handling mechanism of the execution policy used, may call `std::terminate` if an exception is thrown within `f`. Notes:;; Only available in compilers supporting C++17 parallel algorithms. + + This overload only participates in overload resolution if `std::is_execution_policy_v<std::remove_cvref_t<ExecutionPolicy>>` is `true`. + + Unsequenced execution policies are not allowed. 416/10000 · 416

	English Swaps the contents of the table with the parameter. 51/10000 · 51
378 :1570

	English If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the tables' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior. 233/10000 · 233
379 :1573

	English Throws:;; Nothing unless `key_equal` or `hasher` throw on swapping. Concurrency:;; Blocking on `*this` and `other`. 115/10000 · 115

383 :1584

	English Extracts the element with key equivalent to `k`, if it exists. 62/10000 · 62
384 :1587

	English Returns:;; A `node_type` object holding the extracted element, or empty if no element was extracted. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; The `template<class K>` overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs. The library assumes that `Hash` is callable with both `K` and `Key` and that `Pred` is transparent. This enables heterogeneous lookup which avoids the cost of instantiating an instance of the `Key` type. 546/10000 · 546
