e.g.

function such as following

func Do(logger *log.Logger, data DoInput, debug *bool, targetID string) (interface{}, error) {

}

transform to

type Input struct {
    Data     DoInput `json:"data"`
    Debug    *bool   `json:"debug"`
    TargetID string  `json:"targetID"`
}

💭 with embedded option, maybe using data as embedded field

lambda handler is also not having path and query-string, so another handling way for the argument that treated as primitive and primitive-pointer is needed. this is same in the situation using cli.

transform to ??

• func -> reflect.Type ?
• func -> reflectshape.Shape?
• func -> tinypkg.Func?

[podhmo]

func -> reflectshape.Shape is better, I think.

(plus point: reflect-openapi is also using reflect.Shape #122 )

(additional: with raw field ?)

like go-stripe do

validation

hmm https://github.com/podhmo/apikit/issues/147#issuecomment-953762656

if func -> struct transformation automatically, cannot handle validation?

or something like below

g.Generate(pkg, action.Do, WithTag("targetId", `validate: regexp="^[a-f0-9]{24}"`))

or

type ObjectID string
func (id *ObjectId) TagString() string { return `<tag>` }

or
