Made Opt a Variant

[dansteren]

Opts are now either {Some: value} or {None: null}. You can make None values with the helper None const from Azle. Additionally, Some is a helper function for wrapping your values. Call like this: Some(value).

For example:

import { Canister, None, Opt, query, Some, text } from 'azle';

export default Canister({
    returnSomeText: query([], Opt(text), () => {
        return Some('value');
        // equivalent to: return { Some: 'value' };
    }),
    returnNone: query([], Opt(text), () => {
        return None;
        // equivalent to: return { None: null };
    })
});
