导入具有限定名称的联合类型

Question

所以我有两种联合类型：JobStatus 和 TaskStatus。

module Data.Job exposing (..)


type JobStatus
    = Submitted
    | Started
    | Finished

-

module Data.Task exposing (..)


type TaskStatus
    = Created
    | Running
    | Finished

然后我将它们导入第三个模块

module Home exposing (..)


import Data.Job as Job exposing (JobStatus(..))
import Data.Task as Task exposing (TaskStatus(..))


type alias Model =
    { jobStatus : JobStatus
    , taskStatus : TaskStatus
    }


model : Model
model =
    { jobStatus = Finished
    , taskStatus = Finished
    }

但是Finished太乱了，我想写成JobStatus.Finished或者TaskStatus.Finished怎么办？

Answer 1

如果您更改了导入内容

import Data.Job as Job exposing (JobStatus(..))
import Data.Task as Task exposing (TaskStatus(..))

至此

import Data.Job as Job 
import Data.Task as Task

您可以使用 Job.Finished 和 Task.Finished。
