Returns:;; The number of elements erased (0 or 1). Throws:;; Only throws an exception if it is thrown by `hasher`, `key_equal` or `f`. Notes:;; `f` is passed a non-const reference to `x`. + + The `template<class K, class F>` overload only participates in overload resolution if `std::is_execution_policy_v<std::remove_cvref_t<ExecutionPolicy>>` is `false`. + + The `template<class K, class F>` 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.
