func AddRule ¶

func AddRule(name string, ruleFunc RuleFunc)

AddRule adds a rule to the rule set. ruleFunc is called once each time `Validate` is executed.

func IsValidFloatString ¶ added in v2.4.2

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

func IsValidIntString ¶ added in v2.4.2

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

func LoadSchema ¶

func LoadSchema(inputs ...*Source) (*Schema, error)

func PreludeDocument ¶ added in v2.5.64

func PreludeDocument() *ast.SchemaDocument

PreludeDocument returns the parsed Prelude: the built-in scalars, directives and introspection types that LoadSchema adds to every schema. Use it to find out what this version of gqlparser declares, instead of keeping a copy of those names.

Each call parses Prelude again, so the caller owns the result and may modify it. It panics if the embedded prelude does not parse, which is a gqlparser bug.

func QueryIntrospectionFields ¶ added in v2.5.64

func QueryIntrospectionFields() ast.FieldList

QueryIntrospectionFields returns the __schema and __type fields that the spec adds to the query root type. ValidateSchemaDocument appends them to the query type it finds; a caller that supplies its own query type needs them too.

Each call returns new definitions, so the caller owns the result.

func RemoveRule ¶ added in v2.5.18

func RemoveRule(name string)

RemoveRule removes an existing rule from the rule set if one of the same name exists. The rule set is global, so it is not safe for concurrent changes.

func ReplaceRule ¶ added in v2.5.21

func ReplaceRule(name string, ruleFunc RuleFunc)

ReplaceRule replaces an existing rule from the rule set if one of the same name exists. If no match is found, it will add a new rule to the rule set. The rule set is global, so it is not safe for concurrent changes.

func ValidateSchemaDocument ¶

func ValidateSchemaDocument(sd *SchemaDocument) (*Schema, error)

func ValidateWithRules ¶ added in v2.5.29

func ValidateWithRules(
	schema *Schema,
	doc *QueryDocument,
	rules *validatorrules.Rules,
) gqlerror.List

func ValidateWithRulesWithSources ¶ added in v2.5.37

func ValidateWithRulesWithSources(
	schema *Schema,
	doc *QueryDocument,
	rules *validatorrules.Rules,
) gqlerror.SourceList

ValidateWithRulesWithSources is the source-aware counterpart to ValidateWithRules.

func ValidateWithSources ¶ added in v2.5.37

func ValidateWithSources(schema *Schema, doc *QueryDocument, rules ...Rule) gqlerror.SourceList

ValidateWithSources is the source-aware counterpart to Validate. It keeps source documents for every location recorded by the built-in At option while leaving Error and the regular validation API unchanged.

func VariableValues ¶

func VariableValues(
	schema *ast.Schema,
	op *ast.OperationDefinition,
	variables map[string]any,
) (map[string]any, error)

VariableValues coerces and validates variable values.

func Walk ¶

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

Walk is an alias for core.Walk.
