Encountering the same problem

[marsberrys]

using generic type like this, it works

type Result[T any] struct {
	Code     int64  `json:"code"`                                
	ErrorMsg string `json:"err_msg,omitempty"`     
	Data     T      `json:"data,omitempty" swaggerignore:"true"`
}

// @response 200 {object} res.Result{data=xxx}

Maybe we can just add a comprehensive example in the README/examples section?

@ubogdan can we close this issue?
Also, do you know if there's any way we could improve this flow of closing issues?
I'm seeking issues or features to contribute to but a lot of times I've seen that they were already done but the issue is not closed.
Thanks for your help.

version 1.16.4 here, generics still doesn't work, even if the docs says it is....

[alexjplant]

Checking in to say that 1.16.4 doesn't seem to support it either. In my source I'm doing

# snip
// @Success 200 {object} json.Result[json.Event]
#snip
result := json.Result[json.Event]{
		Items:       jsonEvts,
		PageCount:   len(jsonEvts),
		TotalCount:  len(jsonEvts),
		CurrentPage: 1,
	}

and am getting

cannot find type definition: json.Result[json.Event]

when attempting to generate. I tried every version back to swag version v1.8.12 and still no dice. @sdghchj are we all doing something wrong? My usage is pretty much identical to what's in the docs - we'd appreciate any help you can provide!

@alexjplant
I just guess json is an external package, so you may retry the command swag init with an option --parseDependency.

swag init --parseDependency

[alexjplant]

In my case that was it (even though both the handler and package are in internal). Thanks for your help!
