How to obtain a generated parser's source code?

[danaugrs]

How would one go about getting the source code of a generated parser?

I used cargo expand. I put this in a scratch file with extension .rs so my editor provides syntax highlighting:

$ cargo expand > scratch/generated.rs

If you only want documentation for the generated code, the pest book suggests cargo doc will do the trick, but I couldn't get that to work (even using the --all switch). I finally discovered that:

$ cargo doc --document-private-items --no-deps

documents the generated parser code.
