如何将字符串转换为Elixir中的函数(how to convert a string to a function in Elixir)

 我需要将一些函数应用于值的映射。 在最糟糕的情况下，这些函数大约有900个函数，所以我将它们创建为数据库中的记录，并将它们一次加载到地图中。这样我可以创建管理页面来管理所有的转换公式......有一天... 
 
 现在我有他们这样 
 
conversion=%{"0":"Tools.Myfunc1/1","1":"Tools.Myfunc2/1",etc...}
 
 那么我需要在地图声明中应用/执行它们。 
 
 问题是他们是字符串，我得到这个错误 
 
 |>Stream.zip(conversion) |>Enum.map( fn {rawValue, formula} -> convertUsing(rawValue,formula) end)预期函数，得到“myModule.Myfunc / 1” 
 
def convertUsing(value,formula) do
        {h,form}=formula
            value
            |>ieee
            |>form.()
     end

I need to apply some functions to a map of values. The functions are around 900 function in the worst case so i created them as records in a database and load them at once to a map.This way i may create an admin page to manage all the conversion formulas ... one day... 
 
Now I have them like this
 
conversion=%{"0":"Tools.Myfunc1/1","1":"Tools.Myfunc2/1",etc...}
 
then I need to apply/execute them in a map statement.
 
The problem is that they are as strings and i get this error
 
|>Stream.zip(conversion) |>Enum.map( fn {rawValue, formula} -> convertUsing(rawValue,formula) end)  expected a function, got "myModule.Myfunc/1"
 
def convertUsing(value,formula) do
        {h,form}=formula
            value
            |>ieee
            |>form.()
     end
