This session we will delve into the sometimes murky world of procedural macros - showing some of the great tooling available for understanding the code generated, such as cargo expand, and the key building blocks we will need for writing our own.
This session we will delve into the sometimes murky world of procedural macros - showing some of the great tooling available for understanding the code generated, such as cargo expand, and the key building blocks we will need for writing our own.
We will cover how to understand what the macros we are calling actually do, as well creating our own very simple derive macros, building up more complex macros using repeat patterns in quote, and looking at basic error reporting.
This talk explains how Rust debugging actually works: how compiler-generated debuginfo (DWARF/PDB) maps binaries back to source, and how LLDB/GDB interpret that data in practice.
