Struct graphql_tools::validation::rules::overlapping_fields_can_be_merged::OverlappingFieldsCanBeMerged

pub struct OverlappingFieldsCanBeMerged<'a> { /* private fields */ }

Overlapping fields can be merged

A selection set is only valid if all fields (including spreading any fragments) either correspond to distinct response names or can be merged without ambiguity.
