Also, is it possible to make a generic function to cover/convert 512 bits ( [0u8; 64] ), for example. WebThe iter function you use is returning references to the array values which means the array returned by to_le_bytes remains owned by the closure and is dropped on return. This of course then doesn't compile since the returned iterator still has references to the array.

WebRight now, I'm thinking about how to implement the byte code and the VM. The easiest, and "cleanest" approach seems to be to implement operations as enum variants, have the bytecode be a Vec of those, and use a usize as program counter.
