Is your feature request related to a problem? Please describe. A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

Hi, I'm using sax-wasm from rust (it's great 🙏), I'm currently using git submodules, which is working fine, but clearly a proper rust crate would be ideal. (To be clear - a rust crate would be good long term, but I don't actually need it right now)

Secondly, I'm having some trouble setting up a "safe" way to collect nodes of an xml document in rust.

The problem is

pub type EventListener = fn(event: Event, data: &dyn Encode<Vec<u8>>);

The only way I can see to mutate an object in a function which matches this signature is to use a static mut and then unsafe, which isn't ideal.

Maybe I'm missing something obvious, but it would be great to be able to process "event/data"s and mutate a struct without resorting to unsafe.

Describe the solution you'd like A clear and concise description of what you want to happen.

I guess either:

• a Iter interface to SAXParser
• or a compile time flag to change EventListener
• or maybe I'm missing some other solution

Let me know if the request is unclear and I can add specific examples.
