在一个匹配模式中匹配并绑定记录类型的字段？

Question

是否可以在匹配模式语句中匹配并绑定记录类型的字段？

type R = { A:int; B:string }
type R' = R option

let record: R' = .....
match record with
| Some(r) ->
     let a, b = r.A, r.B // Can this row be merged to the match pattern like the tuple example below?
     ....
| None -> ....

期望像下面这样的元组

match record with 
| Some(a, b) -> ....

Answer 1

match record with
| Some({A = a; B = b }) -> ...
