class GraphQL::Execution::VariableValues

Validates and coerces a query’s provided variables in a single pass.

Reading methods (#[], #fetch, #to_h, …) return the values as provided by the client (or the default value from the query string), so that existing callers keep working. Coerced values are available from #coerced_value for the runtime.

Constants

UNEXPECTED_NULL_MESSAGE

Attributes

context [R]

errors [R]

Returns

Array<GraphQL::Query::VariableValidationError> — Any errors encountered when coercing the provided variables
