Types ¶
type InlineRule ¶
type InlineRule interface {
EnterField(ctx *WalkContext, parentDef *ast.Definition, field *ast.Field) gqlerror.List
EnterFragment(ctx *WalkContext, parentDef *ast.Definition, frag ast.Selection) gqlerror.List
EnterDirective(ctx *WalkContext, parentDef *ast.Definition, dir *ast.Directive) gqlerror.List
EnterArgument(ctx *WalkContext, argDef *ast.ArgumentDefinition, arg *ast.Argument) gqlerror.List
}
InlineRule is called by the walker during AST traversal at each node.
type Option ¶
type Option func(*Validator)
Option configures a Validator.
func WithInlineRule ¶
func WithInlineRule(r InlineRule) Option
WithInlineRule adds an inline rule to the validator.
func WithPostRule ¶
WithPostRule adds a post-walk rule to the validator.
type PostRule ¶
type PostRule interface {
Validate(ctx *WalkContext, document *ast.QueryDocument) gqlerror.List
}
PostRule is called after the walker completes its full traversal.
type TypeResolver ¶
type TypeResolver interface {
ForName(ctx context.Context, name string) *ast.Definition
DirectiveForName(ctx context.Context, name string) *ast.DirectiveDefinition
QueryType(ctx context.Context) *ast.Definition
MutationType(ctx context.Context) *ast.Definition
SubscriptionType(ctx context.Context) *ast.Definition
PossibleTypes(ctx context.Context, name string) iter.Seq[*ast.Definition]
Implements(ctx context.Context, name string) iter.Seq[*ast.Definition]
}
TypeResolver resolves types and directives from the schema. Matches a subset of schema.Provider methods but is defined here to avoid circular dependency between pkg/schema and pkg/schema/validator.
type Validator ¶
type Validator struct {
// contains filtered or unexported fields
}
Validator validates and enriches GraphQL query documents. Rules are injected via the constructor.
func New ¶
New creates a Validator with the given rules. Without options the validator only performs enrichment (no validation checks). For standard usage: New(DefaultRules()...)
func (*Validator) Validate ¶
func (v *Validator) Validate(ctx context.Context, provider TypeResolver, document *ast.QueryDocument) gqlerror.List
Validate walks the QueryDocument, enriches the AST, and applies validation rules. The document is mutated: field.Definition, field.ObjectDefinition, etc. are filled in. Returns a list of errors (empty = valid).
type WalkContext ¶
type WalkContext struct {
Context context.Context
Provider TypeResolver
Document *ast.QueryDocument
CurrentOperation *ast.OperationDefinition
}
WalkContext provides context accessible to all rules during validation.
