Modern embedded isn't your grandpa's embedded anymore. Modern embedded chips have multiple KiB of ram, some even above 1MiB and have been like that for almost a decade (look at ESP32 for instance). I once worked on embedded projects based on ESP32 that used full C++, with allocators, exceptions, ... using SPI RAM and worked great. There's a fantastic port of ESP-IDF on Rust that Espressif themselves is maintaining nowadays, too.
