From fe43f5294e349097baf0bf4aefb74afedec49429 Mon Sep 17 00:00:00 2001 From: DrDru Date: Wed, 21 Feb 2018 08:29:26 +0100 Subject: [PATCH] Add import scala.language.implicitConversions "import scala.language.implicitConversions" with the current version of Scala. Otherwise I receive an error message when I run the function definition : "advanced_type.scala:11: warning: implicit conversion method strToInt shoulnabled by making the implicit value scala.language.implicitConversions visible. This can be achieved by adding the import clause 'import scala.language.imConversions' or by setting the compiler option -language:implicitConversions. See the Scaladoc for value scala.language.implicitConversions for a discus why the feature should be explicitly enabled." --- web/advanced-types.textile | 2 ++ 1 file changed, 2 insertions(+) diff --git a/web/advanced-types.textile b/web/advanced-types.textile index 3d3ea62c..cf23059a 100644 --- a/web/advanced-types.textile +++ b/web/advanced-types.textile @@ -23,6 +23,8 @@ Sometimes you don't need to specify that one type is equal/sub/super another, ju *Implicit* functions allow automatic conversion.
