## Example

```purs

main = do

  let

    fruits =

      { apple: "great"

      , banana: "good"

      }

    key1 = "apple"

    key2 = "durian"

    key3 = "banana"

    matchString :: String -> Maybe String

    matchString = S.matchString

      { apple: \k -> Record.get k fruits

      , banana: \k -> Record.get k fruits

      }

    result1 = matchString key1

    result2 = matchString key2

    result3 = matchString key3

  assertEqual { actual: result1, expected: Just "great" }

  assertEqual { actual: result2, expected: Nothing }

  assertEqual { actual: result3, expected: Just "good" }

```
