getting the same issue. updating `cortex_m` to `0.6.3` stops the panic, but I can't seem to create MonoTimer with the crated updated.

update - replacing `f3` with `stm32f3xx-hal` more or less got it working, with the caveat that in `main.rs` setting `w.tdr().bits()` now needs to be wrapped in an `unsafe` block. Also...

This probably will involve storing nodes/neighbors as just `String` in the index, then performing lookups in the cache. If node isn't in the cash then load from redis
