NiaLinaLunaStorm: > <@fly:asra.gr> I'm new to rust and fail to convert a buffer `let mut buf = [0u8, 64];` which is the buffer I read stuff into from a serial interface to an integer. I've found stuff but that's uses std and the stm32f1 examples I've looked at and worked from have no_std
> any solution for this?

What I most often use is:

```rust
let buffer = // ...;

let my_int = u32::from_le_bytes(buffer[4..8].try_into().unwrap());
```
