Functions

func EscapeJsonPointer 

func EscapeJsonPointer(p string) string

func GenerateOpenAPIV3OneOfSchema 

func GenerateOpenAPIV3OneOfSchema(types []string) (oneOf []spec.Schema)

GenerateOpenAPIV3OneOfSchema generate the set of schemas that MUST be assigned to SchemaProps.OneOf

func OpenAPITypeFormat 

func OpenAPITypeFormat(typeName string) (string, string)

This function is a reference for converting go (or any custom type) to a simple open API type,format pair. There are two ways to customize spec for a type. If you add it here, a type will be converted to a simple type and the type comment (the comment that is added before type definition) will be lost. The spec will still have the property comment. The second way is to implement OpenAPIDefinitionGetter interface. That function can customize the spec (so the spec does not need to be simple type,format) or can even return a simple type,format (e.g. IntOrString). For simple type formats, the benefit of adding OpenAPIDefinitionGetter interface is to keep both type and property documentation. Example: 

type Sample struct {
     ...
     // port of the server
     port IntOrString
     ...
}

// IntOrString documentation... type IntOrString { ... }

Adding IntOrString to this function: 

"port" : {
          format:      "string",
          type:        "int-or-string",
          Description: "port of the server"
}

Implement OpenAPIDefinitionGetter for IntOrString: 

"port" : {
          $Ref:    "#/definitions/IntOrString"
          Description: "port of the server"
}

... definitions: 

{
          "IntOrString": {
                    format:      "string",
                    type:        "int-or-string",
                    Description: "IntOrString documentation..."    // new
          }
}

func OpenAPIZeroValue 

func OpenAPIZeroValue(typeName string) (interface{}, bool)

Returns the zero-value for the given type along with true if the type could be found.
