Module command 

The Command trait and the DynCommand helper.

A Command pairs a string identifier with a typed request/response pair and an async handler. For compile-time commands, the #[command] attribute macro generates the trait impl; for runtime-constructed commands (plugin runtimes, FFI, scripting hosts), DynCommand lets you build a Command instance whose id / description / schema are owned at runtime.

Structs

DynCommand

A runtime-constructed Command. Use this when the command id or schema is only known at runtime (plugin runtimes, FFI, scripting hosts).

Traits

Command

A typed command handler registered with a CommandRegistry.

Type Aliases

BoxedDynCommand

A DynCommand with fully erased handler types — request and response are serde_json::Value, the handler is a boxed async closure. Use when you need to store a heterogeneous collection of runtime commands (e.g. Vec<BoxedDynCommand> inside a plugin host).

BoxedHandler

Type-erased async handler for a BoxedDynCommand: takes and returns raw JSON Values.
