Unrolled.jl:在编译时展开循环

展开 Unrolled.jl 提供了在编译时长度已知的序列（主要是Tuple和 ）上展开循环的函数。 这可以显着提高性能和类型稳定性。 @unroll宏 julia > using Unrolled julia > @unroll function my_sum (seq) # More on why we need @unroll twice later. total = zero ( eltype (seq)) @unroll for x in seq total += x end return total end my_sum_unrolled_expansion_ (generic function with 1 method) julia
