These implement the Binding interface and can be used to bind the data present in the request to struct instances.

var EnableDecoderUseNumber = false

EnableDecoderUseNumber is used to call the UseNumber method on the JSON Decoder instance. UseNumber causes the Decoder to unmarshal a number into an interface{} as a Number instead of as a float64.

type Binding Uses

type Binding interface {
    Name() string
    Bind(*http.Request, interface{}) error

Binding describes the interface which needs to be implemented for binding the data present in the request such as JSON request body, query parameters or the form POST.

func Default Uses

func Default(method, contentType string) Binding

Default returns the appropriate Binding instance based on the HTTP method and the content type.

type BindingBody Uses

type BindingBody interface {
    BindBody([]byte, interface{}) error

BindingBody adds BindBody method to Binding. BindBody is similar with Bind, but it reads the body from supplied bytes instead of req.Body.

type StructValidator Uses

type StructValidator interface {
    // ValidateStruct can receive any kind of type and it should never panic, even if the configuration is not right.
    // If the received type is not a struct, any validation should be skipped and nil must be returned.
    // If the received type is a struct or pointer to a struct, the validation should be performed.
    // If the struct is not valid or the validation itself fails, a descriptive error should be returned.
    // Otherwise nil must be returned.
    ValidateStruct(interface{}) error

    // Engine returns the underlying validator engine which powers the
    // StructValidator implementation.
    Engine() interface{}

StructValidator is the minimal interface which needs to be implemented in order for it to be used as the validator engine for ensuring the correctness of the reqest. Gin provides a default implementation for this using

var Validator StructValidator = &defaultValidator{}

Validator is the default validator which implements the StructValidator interface. It uses under the hood.
