В предыдущих главах мы познакомились с АТД, которые сами по себе уже весьма полезны. И всё же есть в них одно ограничение: они напрочь лишены гибкости. Вот тебе конкретные поля, а вот тебе конкретные типы, будь счастлив. Но существует способ наделить наши тип куда большей силой. Эта глава станет для нас переломной, ведь с неё начнётся наш путь в мир действительно мощных типов.- Read upRead up

This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.
This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.
You also have the option to exclude this rule for code blocks and tables. To
do this, set the code_blocks and/or tables parameters to false.
Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.

В самом деле, почему? Например, в Haskell широкое применение получил тип `Text` из одноимённого пакета. Этот тип, кстати, значительно мощнее и эффективнее стандартной `String`. Значит, если мы захотим определить опциональный тип и для `Text`, придётся дублировать:- Read upRead up

Применение конструктора типа к существующему типу порождает некий новый тип, и это очень мощная техника, используемая в Haskell почти на каждом шагу. Например, если нам нужно завернуть в опциональное значение уже не `String`, а ранее упомянутый `Text`, мы ничего не должны менять в конструкторе `Maybe`:- Read upRead up

А вот на втором и последующих этажах живут типы куда более интересные. Например, на одном из этажей живёт тип `Maybe String`. При создании типа `Maybe String` происходит важное событие: мы поднимаемся с первого на более высокий этаж. Считайте эти этажи уровнями абстракции. Если тип `String` — это всего лишь безликая строка, то тип `Maybe String` — это уже не просто строка, это опциональная строка, или, если хотите, строка, наделённая опциональностью. Подняться на тот или иной этаж в нашем типовом небоскрёбе — это значит взять более простой тип и наделить его новым смыслом, новыми возможностями.- Read upRead up

На самом нижнем этаже расположены простейшие стандартные типы, такие как `Int`, `Double`, `Char` или список. Возьмём, например, тип `Int`. Что это такое? Целое число. Оно не несёт в себе никакого смысла, это всего лишь число в вакууме. Или вот строка — что она такое? Это просто набор каких-то символов в том же вакууме, и ничего более.

Я обещал рассказать о том, что такое `IO`, и вот теперь рассказываю: `IO` — это тоже конструктор типа. Правда, конструктор особенный, непохожий на наши `IPAddress` или `EndPoint`, но об этом подробнее в следующих главах. Так вот поднявшись на этаж под названием `IO`, мы получаем очень важную способность — способность взаимодействовать с внешним миром: файл прочесть, на консоль текст вывести, и в том же духе. И потому тип `IO String` — это уже не просто невесть откуда взявшаяся строка, но строка, полученная из внешнего мира (например, из файла). И единственная возможность наделить наши функции способностью взаимодействовать с внешним миром — поднять (ну или опустить) их на `IO`-этаж.

This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.
This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.
You also have the option to exclude this rule for code blocks and tables. To
do this, set the code_blocks and/or tables parameters to false.
Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.
