Index Design of the Rustdoc

• This index section is only available for structs yet.
• The whole index should be put under the type documentation of a struct in the documentation body, and collapsed by default.
• Auto and blanket trait implementations are not separated from normal traits.
• The pub modifier is omitted by default, maybe we can display it when --private-items flag is enabled.
• Trait bounds for generic parameters are omitted
• The type for const generic parameters are omitted.
• Each table is not necessarily rendered as tables in HTML, they can be rendered like the summary of a module, and the headers are not necessary as well.
• We might also add a button on the top right (beside the [+] button) for jumping to the index, in case the type documentation is too long.
