Needs Documentation: More examples

[daniel-samson]

Description

we should have more real world examples, for slices etc. Perhaps we need an example directory

Context

I think it would help users see the benefit of this crate compared to other crates

[moh-abk]

Lack of examples is what is preventing me from using this crate. I'm using Postgres with https://github.com/launchbadge/sqlx

Examples should be both from the backend developer perspective but also the frontend developer. I'm trying to implement a similar pagination to this - https://developer.atlassian.com/server/confluence/pagination-in-the-rest-api/
