We don't actually need this to be a trait; we just need
methods and objects to have a `CONST_TYPE_ID_` if they want to
participate in the inventory-based method registry.
Removing this trait makes it much simpler to declare methods and
objects.

This simplifies our implementation logic in a few places,
and simplifies our invocation syntax greatly. There are a few
infelicities, noted in `TODO RPC` comments.

This is a rather tricky piece of functionality. It works as
follows.
We introduce a `CastTable` type. Each `CastTable` tells us how to
downcast `dyn Object` for objects of a single concrete type.
The `Object` type now has a `get_casttable` method that returns
an empty `CastTable` by default.
`CastTable` is, internally, a map from the `TypeId` of the target
dyn Trait reference type to a function
`fn(&dyn Object) -> &dyn Trait`. These functions are stored as
`Box<dyn Any + ...>`. (They are Boxed because they may refer to
generic functions, which you can't get a static reference to,
and they're Any because the functions have different types.)
The `decl_object!` macro now implements `get_casttable` as
appropriate. (The syntax is a bit janky, but that's what we get
for not using derive_adhoc.) For non-generic types, `get_casttable`
uses a Lazy<CastTable>`. to initialize a CastTable exactly once.
For generic types, it use a `Lazy<RwLock<HashMap<..>>` to
build one CastTable per instantiation of the generic type.
This could probably be optimized a bit more, the yaks could be
shaved in a more scintillating hairstyle, and the syntax for
generic `decl_object` could definitely be improved.

Rationale: Our weak-vs-strong design is a bit confused at the moment
due to concerns about deduplication and capability semantics. It's
not clear that a general "change strong to weak" method is
compatible with what we want to provide.

I've made doing some design choices here:
* Reserving "rpc" as a prefix for post-authentication
functionality that is not arti-specific.
* Declaring these to be methods on the session rather than methods
on the objects themselves.
There's a problem with defining an API to drop a weak reference; see
comment in code.

Right now, this lets us say whether the method was unrecognized or
whether the parameter type was incorrect.
We'll use this to enforce correct method names later on.
(I have to add another `inventory` here, since the `typetag`
maintainer does not want to expose this functionality: see
https://github.com/dtolnay/typetag/issues/57#issuecomment-1506106290
)

Now `Method` has an Output and Update associated type, and
`decl_method` can do a little more.
|
| |
|
|
|
| |
Now the update sink is its own boxed object. It is not yet passed
to the invoke functions that want it.
