any type (generics)

[kbakdev]

Does swagger will support any type from generics?

[youyuanwu]

For what use case? example?

[kbakdev]

If, for example, we can get a variety of data from a response, a wrapper that can wrap all such data would be useful. This can replace interface{}, for example, and work better.

Example:

// swagger:model transportErr
type transportErr struct {
   // Message is a human-readable description of the error.
   // Required: true
   Message string `json:"message"`
   // Data is additional data about the error.
   Data any `json:"data,omitempty"` // <- for this use case. Unsupported type "invalid type"
}

I thought any is an alias for interface{}. Are you asking us to replace interface{} by any in all code and the generated code?

[casualjim]

I think what is being asked is to support any in the codescan package, to recognize it the same way we recognize interface{} today

[amit-mahendrakar]

The v0.29.0 generator does not understand any type.

If we try to use fields of type any in query or body, the generator gives error

unsupported type "invalid type"

because it sees any as invalid type

I think this is what @casualjim is asking.

@youyuanwu is there a plan to support it ?

[amit-mahendrakar]

whereas if we just change the type of parameter from any to interface{}, generation is successful.

[jesse-schneider]

Also would like to know if there are plans to include this in the future?

[casualjim]

I added some tests for where we have the type interface{}, all the tests we have for the codescan package pass.
I've also added the transportErr type from this issue. https://github.com/go-swagger/go-swagger/blob/8edb8ee718461ce941a04a235689f1b83431e0f0/fixtures/goparsing/go118/nomodel.go

I think you may get it to work with previous versions of go swagger by building from source with a newer golang like go 1.18.
