Overview

Package types provides implementations of all GraphQL built in types.

As a convenience, the types in this package are Scannable from SQL and Unmarshalable from JSON (as well as providing fast unmarhshalling via jsoniter) so that they can be used to directly map data from a database or JSON speaking service.

Variables

View Source 
var PermissiveInputCallback = func(typ string, value schema.LiteralValue) {}

PermissiveInputCallback is a callback that is notified when a value is accepted via permissive parsing

View Source 
var PermissiveInputParsing = false

PermissiveInputParsing allows more input value conversions than allowed by the spec if set to true
