## Worth considering using it in a single provider, many requester scenario.
##
## Provides a declarative way to define an immutable value type together with a
## thread-local broker that can register an asynchronous provider, dispatch typed
## requests and clear provider.
## thread-local broker that can register an asynchronous or synchronous provider,
## dispatch typed requests and clear provider.
##
## For consideration use `sync` mode RequestBroker when you need to provide simple value(s)
## where there is no long-running async operation involved.
## Typically it act as a accessor for the local state of generic setting.
##
## `async` mode is better to be used when you request date that may involve some long IO operation
## or action.
##
## Usage:
## Declare your desired request type inside a `RequestBroker` macro, add any number of fields.

## proc signature*(arg1: ArgType, arg2: AnotherArgType): Future[Result[TypeName, string]]
##
## ```
##
## Sync mode (no `async` / `Future`) can be generated with:
##
## ```nim
## RequestBroker(sync):
## type TypeName = object
## field1*: FieldType
##
## proc signature*(): Result[TypeName, string]
## proc signature*(arg1: ArgType): Result[TypeName, string]
## ```
##
## Note: When the request type is declared as a native type / alias / externally-defined
## type (i.e. not an inline `object` / `ref object` definition), RequestBroker
## will wrap it in `distinct` automatically unless you already used `distinct`.
## This avoids overload ambiguity when multiple brokers share the same
## underlying base type (Nim overload resolution does not consider return type).
##
## This means that for non-object request types you typically:
## - construct values with an explicit cast/constructor, e.g. `MyType("x")`
## - unwrap with a cast when needed, e.g. `string(myVal)` or `BaseType(myVal)`
##
## Example (native response type):
## ```nim
## RequestBroker(sync):
## type MyCount = int # exported as: `distinct int`
##
## MyCount.setProvider(proc(): Result[MyCount, string] = ok(MyCount(42)))
## let res = MyCount.request()
## if res.isOk():
## let raw = int(res.get())
## ```
##
## Example (externally-defined type):
## ```nim
## type External = object
## label*: string
##
## RequestBroker:
## type MyExternal = External # exported as: `distinct External`
##
## MyExternal.setProvider(
## proc(): Future[Result[MyExternal, string]] {.async.} =
## ok(MyExternal(External(label: "hi")))
## )
## let res = await MyExternal.request()
## if res.isOk():
## let base = External(res.get())
## echo base.label
## ```
## The 'TypeName' object defines the requestable data (but also can be seen as request for action with return value).
## The 'signature' proc defines the provider(s) signature, that is enforced at compile time.
## One signature can be with no arguments, another with any number of arguments - where the input arguments are

##
## After this, you can register a provider anywhere in your code with

## Providers are async procs/lambdas in default mode and sync procs in sync mode.
