Functions

func AddRule

func AddRule(name string, f ruleFunc)

addRule to rule set. f is called once each time `Validate` is executed.

func IsValidFloatString

func IsValidFloatString(val reflect.Value, kind reflect.Kind) bool

func IsValidIntString

func IsValidIntString(val reflect.Value, kind reflect.Kind) bool

func OrList

func OrList(items ...string) string

Given [ A, B, C ] return 'A, B, or C'.

func QuotedOrList

func QuotedOrList(items ...string) string

Given [ A, B, C ] return '"A", "B", or "C"'.

func SuggestionList

func SuggestionList(input string, options []string) []string

Given an invalid input string and a list of valid options, returns a filtered list of valid options sorted based on their similarity with the input.

func Validate

func VariableValues

func VariableValues(schema *ast.Schema, op *ast.OperationDefinition, variables map[string]interface{}) (map[string]interface{}, *gqlerror.Error)

VariableValues coerces and validates variable values

func Walk

func Walk(schema *ast.Schema, document *ast.QueryDocument, observers *Events)
