I know that in SCALA I can convert a type to another by define some implicit function, my question is , how can I know what conversions can I use after importing tons of packages?
For example, I have a string, and than how can I know what types can it convert to ?
Edit to clarify, I wanna do it in my scala compile plugin, so I may need to call a function on a reflect.api.tree type, and then get the implicits. I am looking some method to use the implicitly mentioned in the answer.
In the REPL you can invoke
:implicits to see all the in-scope implicits other than those available from the Predef. (Add
-v to see Predef implicits as well.)
You can also invoke the
implicitly function from anywhere in your code to test for particular implicits.
