Generated code

This page walks through the “Hello, World!” example and explains the code that it generates. Please take it with a grain of salt: while we make an effort to keep this documentation up to date, this sort of thing can fall out of date easily. See the page history below for major updates.

If you'd like to see for yourself, you can set the environment variable SALSA_DUMP to 1 while the procedural macro runs, and it will dump the full output to stdout. I recommend piping the output through rustfmt.
