Crate standout_dispatch 

Command dispatch and orchestration for clap-based CLIs.

Routes parsed ArgMatches to a Handler, running pre-dispatch, handler, post-dispatch, and post-output hooks around it, and returns typed HandlerResult data — presentation stays with the consuming framework. A handler adapter takes (&ArgMatches, &CommandContext) and returns serializable data, so application logic stays reusable outside a CLI. The third parameter of Handler::handle is the typed results channel of [results]; a batch command sets Handler::Event to NoEvents and ignores it, and a command that produces its result while it runs takes the channel as a third closure parameter through EventsFnHandler.

CommandContext carries two kinds of injected state: app_state is immutable and app-lifetime (database, config, API clients), built once and shared via Rc; extensions is mutable and per-request, set by pre-dispatch hooks for things like a resolved user session.

Envelope

EventsFnHandler

The adapter behind a three-argument closure, whose third parameter is the command’s typed results channel, so Event is the closure’s event type.

Results

The handler’s channel for the values a command produces while it runs.

RunError

RunOutput

RunRecorder

Retains the run’s result values and its delivery decision.

Enums

Delivery

Where the run’s rendered bytes went. Pager carries the shell word list the environment named, decided without starting the pager.

DispatchResult

EmitError

HookPhase

NoEvents

The event type of a command that emits none: uninhabited, so emit has no argument that can be constructed.

Summary

What a command that declares events returns once the events are done: they already carried the run’s results, so a payload has nowhere left to go.

Traits

ContractSurface

EventSink

The representation’s destination for one emitted event.

Handler

HandlerOutcome

What Handler::handle may return, tied to the command’s event type: Output<T> is an outcome only for NoEvents, so a command that declares events has Summary<T> and no payload variant to return.

IntoHandlerResult

IntoSummaryResult

Functions

emits_events

Whether a command whose Handler::Event is E produces its result while it runs: false for NoEvents and true for every other event type.
