Bytes in std::io - Rust
WebI should preface my comments with the fact that I'm pretty unfamiliar with this part of Rust; there may be better ways. Read::take() with Read::read_to_end() is useful here. Note that repeated take() s to the file require Read::by_ref() , since take() is by-value. 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. A stack frame would be a type StackFrame = HashMap and the stack would be a Vec. bajarons
