Performs an operation using aManager, then closes theManager, releasing its resources (in reverse order of acquisition).
Example:
val lines = Using.Manager { use => use(new BufferedReader(new FileReader("file.txt"))).lines()}If using resources which require an implicitManager as a parameter, this method should be invoked with animplicit modifier before the function parameter:
Example:
val lines = Using.Manager { implicit use => new SafeFileReader("file.txt").lines()}See the main doc forUsing for full details of suppression behavior.
