Quill, Dotty, And The Awesome Power of 'Inline' by Alexander Ioffe

Alexander Ioffe demonstrates how Scala 3's inline keyword and macros are used to rebuild the Quill library for compile-time query generation.

Scala 3 is arriving, and with it comes incredible new power for library authors. In this presentation, Alexander Ioffe, a contributor to Quill (a LINQ-like persistence layer for Scala), will show how using Scala 3 Macros, Quill is being rebuilt to be better, stronger, and faster. As you will learn in this presentation, Scala 3 introduces a new powerhouse keyword called 'inline' that opens up a new continent of capability. This construct powers all Scala 3 macros, and allows users to interact with staged code almost indistinguishably from normal code, allowing familiar patterns such as global-methods, type-classes, and type-level-logic. For Quill, Alexander will show how this allows generating compile-time SQL using patterns that we once only dreamed about using--and these features just scratch the surface of what can be done with staged code. Come discover the bright future of powerful, type-safe libraries in Scala 3!
