// Command is an HandlerAdapter that returns a server.HandlerFunc that

// The command adapters are used to handle commands that do not accept a body
|
|
// or a query. You can think of them as a way to handle RPC style Rest Endpoints.
|
|
//
|
|
// Example:
|
|
//
|
|
// fn := func(ctx context.Context) (interface{}, error) {
|
|
// // do something
|
|
// return nil, nil
|
|
// }

|
// r.Get("/foo", adapters.Command(fn, http.NoContent))

|
|
// in the URL. The parameter name is passed as the first argument.

|
//
|
|
// fn := func(ctx context.Context, id uuid.UUID) (interface{}, error) {
