append(mapFn(item)) catch {}; } return fb; } }; Zig语言实现的这个Functor类型类使用起来是比较简单的。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。
append(b) catch break; } } return mb; } }; 使用这个ArrayList的Monad类型类实例的方式和Haskell中的一样,不同的地方还是匿名函数和闭包需要包裹在struct中才可以使用。具体代码如下: // example of applicative functor const FloatToIntFn = *const fn (f64) u32; const fn_array = [_]FloatToIntFn...

The point here is that Value is representing an array type value and not an array value.If there is still some confusion, look at the toValue function defined for Type. A Type can always be converted a value, because a type can be a value, but the reverse is not always true....
