先调用Functor这个类型函数创建一个ArrayListFunctor类型,并使用allocator初始化得到一个Fiunctor实例array_f。然后通过这个实例调用fmap接口函数,传入转换函数map,这样就得到一个新的转换后的ArrayList了。这个例子中,分别先后使用了inplace和new value这两个不同版本的fmap接口函数的实现。可以看到使用inplace版本的fmap...
a => |*byte| byte.* += 1, .b => |*float| float.* *= 2, .c => |*b| b.* = !b.*, } std.debug.print("v2 = {}\n", .{value2}); } 差不多没了。可能还有个比较常用的就是ArrayList。 剩下的看文档吧。发布于 2024-03-13 14:45・陕西 zig 编程语言 Rust(编程语言)...

Can't figure out how to array access an ArrayList. I get a compile error of: error: array access of non-array type 'std.array_list.ArrayListAligned(u32,null)'. That sure seems like an array type to me. Need to access myArray.items[idx] instead of myArray[idx]. I get it. But...
