• Defined in File unrolled_for.hpp

Function Documentation

template<size_t Amount, typename Functor, typename ...Args, unroll_enabled_t<Amount> = 0>
constexpr auto ripple::unrolled_for_bounded(Functor &&functor, Args&&... args) noexcept -> void

Applies the functor Amount times.

However, this is a bounded version and is safer than unrolled_for in that it will not unroll if the value of Amount is larger than the value defined by ripple_max_unroll_depth at compile time.

In the case that Amount is larger than ripple_max_unroll_length then a normal loop is performed and the functor is invoked on each iteration.

This overload is only enabled when

Amount < ripple_max_unroll_depth.

Note

This version will not always use a constexpr index, and therefore the index cannot be used in constexpr contexts.

However, this is a bounded version and is safer than

unrolled_for in that it will not unroll if the value of Amount is larger than the value defined by ripple_max_unroll_depth at compile time.

Parameters

• functor: The functor to unroll.

• args: The arguments to the functor.

Template Parameters

• Amount: The amount of unrolling to do.

• Functor: The type of the functor.

• Args: The type of the functor arguments.

Parameters

• functor: The functor to unroll.

• args: The arguments to the functor.

Template Parameters
