i'm not surprised considering how insanely complex rust grammar is.

idk which IDE you use but rustrover would let you try out Junie and junie is the bees knees of coding agents. these "AI" tools are not coding agents. junie makes plans, runs commands, parses logs, and feeds back, updating its plan and continuing until it thinks the task is finished. it helps to tell it to write tests to validate corrrectness.
