[T1] Modify the dispatcher! Syntax

+

+ Breaking: drop the CMD* struct from the explicit form of dispatcher! +

+ +> [!NOTE] +> +> This is a **Breaking Change** planned for Mingling 0.5.0, and it depends on [Remove with_dispatcher and with_dispatchers](t0_remove-with-dispatcher). + +## Background + +Once `Dispatcher` registration is compile-time collected (see [Remove with_dispatcher and with_dispatchers](t0_remove-with-dispatcher)), the `CMD*` struct becomes unnecessary — it only existed to give `with_dispatcher` something to register. + +## Plan + +Simplify the `dispatcher!` syntax: the explicit form no longer creates a `CMD*` struct, so only the entry type needs to be given. + +```rust +// Before +dispatcher!("command", CMDCommand => EntryCommand); + +// After +dispatcher!("command", EntryCommand); + +// NOTE: The implicit mode is not affected +``` + +## Tasks + +- [ ] Update `dispatcher!` to accept the simplified explicit form (`"name", EntryType`) +- [ ] Decide whether the old `CMDType => EntryType` form should error with a helpful message or be removed outright +- [ ] Remove the generated `CMD*` struct machinery +- [ ] Update `#[command]` macro internals that depend on `CMD*` +- [ ] Migrate examples, tests, and docs +- [ ] Keep the implicit mode (`dispatcher!("name")`) working unchanged + +## 🕘 Progress + +- [ ] In Progress +- [ ] Complete + +
