>Rust does everything C++ does, as far as things happening invisibly

These 4 things do not happen invisibly in rust:

code running on struct creation (it will be an explicit ::new() call)

code running on struct copying (it will be an explicit ::clone() call)

code running on struct moving (moving is always a memcpy in rust, no custom code can run).

Error handling flow control (no exceptions, error handling will at minimum be marked with a '?'). (yes panic exists but this is basically for the same purposes as a kernel panic).

Rust favours making things explicit, much more so than C++.
