F#参数传递 [英] F# parameter passing

问题描述

我一直认为F#有两种不同的传递参数的方式:咖喱风格和元组风格. 这真的正确吗?

I've always thought that F# had two different ways to pass arguments, curry style and tuple style. Is this actually correct?

不是一种样式，咖喱样式和参数都可以是简单值或元组.

Isn't it simply one style , curry style, and arguments can either be simple values or tuples.

例如

someFunc (a,b) =

这不是带有 one 咖喱风格参数的函数，恰好是一个元组吗? 因此，我可以使用pipleline运算符将元组传递给此函数吗? (元组元素的命名位置)

isn't this a function with one curry style argument which happens to be a tuple ? Thus allowing me to pass tuples to this function using the pipleline operator? (where the elements of the tuple is named)

(1,2) |> someFunc

这正确吗?

推荐答案

这将很好用-区别在于您拥有

This will work just fine - the difference is when you have

let f (a,b) = ...
let f2 a b = ...

然后，您可以轻松创建部分应用的f2，但是对于f来说，效果却不太理想-您必须这样做

then you can create a partially applied f2 easily, but for f it doesn't work quite as nicely - you have to do

let partial = fun t -> f (1,t)
let partial2 = f2 1
