FWIW. Claude Code does great job for me on complex domain Rust projects, but I just use it one relatively small feature/code chunk at the time, where oftentimes it can pick up existing patterns etc. (I try to point it at similar existing code/feature if I have it). I do not let it write anything creative where it has to come up with own design (either high-level architectural, or low level facilities). Basically I draw the lines manually, and let it color the space between, using existing reference pictures. Works very, very well for me.
