Functions

func Bind

func Bind(c *gin.Context, obj interface{}, bindFuncs ...func(*gin.Context, interface{}) error) error

Bind processes data from multiple sources without validating between each step, then performs a single validation at the end.

This solves the problem where binding from one source (e.g., URI) fails validation because fields from another source (e.g., JSON) haven't been bound yet.

Example usage:

var req UserUpdateRequest
if err := binding.Bind(c, &req, binding.URI, binding.JSON); err != nil {
    c.JSON(http.StatusBadRequest, ErrorResponse{Message: err.Error()})
    return
}

func JSON

func JSON(c *gin.Context, obj interface{}) error

JSON binds JSON body to the given object. Uses Gin's ShouldBindJSON but without validation.

func URI

func URI(c *gin.Context, obj interface{}) error

URI binds URI parameters to the given object. Uses Gin's ShouldBindUri but without validation.
