Variables

var ErrUnsupportedType = errors.New("unsupported type")

ErrUnsupportedType is an error that indicates that there is no conversion function for the requested type.

Types

type FnMap

type FnMap map[string]reflect.Func

FnMap is a mapping between type names and appropriate conversion functions.

func Context

func Context() FnMap

Context returns mappings between types that can be parsed using strconv package and functions for that conversions. All conversion functions meet the following criteria: 1. They are exported. 2. They expect 3 arguments: url.Values, string, ...int. 3. They return 1 argument. This is useful for code generation.

func (FnMap) Render

func (m FnMap) Render(pkgName, vsName string, a reflect.Arg) (string, error)

Render gets a package name, name of url.Values variable and an argument, and renders an appropriate strconv Function, e.g. `strconv.Int(r.Form, "number")`. If the argument is not supported error will be returned as a second argument. This is used for code generation.
