Examples of how to use please

[gilescope]

As a dev,
Given I want to make cool stuff in polkadot,
When I go to the repo,
Then I expect to see a good example of

• how to decode bytes to a type statically ( storage, event, extrinsic )
• how to decode bytes to some dynamic structure (or can we do rust amazing trick of visit the bytes without decoding / borrowing bits using lifetimes?)
• how to encode something to bytes (I think people will have the least difficulty with this).

We have docs at many levels but some well placed examples here would go a long way. Either on the readme or in an examples dir would be where I would be looking for these.

This is a long standing issue assigned to me, see polkadot-developers/substrate-docs#385 and use-ink/ink#940.

I suppose I'd better get on it.

Pointers to example use cases might be enough... for the dynamic decoding case https://docs.rs/desub-current/latest/desub_current/value/index.html is maybe a good example of using frame-metadata?
