How to use the indexed_db via web-sys

[bigfish3000]

How to use the indexed via web-sys, do some one have examples ?

Who can show me the examples?

I can not access the indexed_db like this:

        let db = window!().indexed_db().unwrap().unwrap();
        let opened_request = match db.open("test-my") { 
            Ok(v) => { v },
            Err(res) => { 
                let s = Array::from(&res);
                console::log(&s);
                return;
            }
        };
        let trans = match opened_request.transaction() {  
            Some(v) => { v },
            None => { 
                log_info_str!("Can not get transaction"); //It always show me error!
                return;
            }
        };
        let db = trans.db();
        let store = match db.create_object_store("my-test") { 
            Ok(v) => { v },
            Err(err) => {                 
                let s = Array::from(&err);
                console::log(&s);
                return;
            }
        };
        let js = JsValue::from("hello world");
        let _request = match store.put(&js)  { 
            Ok(v) => { v },
            Err(err) => {                 
                let s = Array::from(&err);
                console::log(&s);
                return;
            }
        };

indexeddb is quite complicated. Everything is done async via. callbacks, so you need to use Closure, but the memory management is fiddly. Eventually there will be a futures-based lib in https://github.com/rustwasm/gloo, in the mean time it's just gonna be hard.

Thanks for the question @bigfish3000! I agree with @derekdreery in that this is pretty complicated, but targeted to be covered by the gloo project! In light of that I'm gonna close this in favor of rustwasm/gloo#68
