Functions

func CheckNoDuplicateKeysFor 

func CheckNoDuplicateKeysFor(data []byte, target reflect.Type) error

CheckNoDuplicateKeysFor rejects repeated object keys. When an object is decoded into a struct, keys are compared with encoding/json's case-folding rules so two spellings cannot silently target the same field.

func CheckNoDuplicateKeysForSchema added in v0.60.2 

func CheckNoDuplicateKeysForSchema(data []byte, schema reflect.Type) error

CheckNoDuplicateKeysForSchema traverses an explicit typed schema, folding only known field names. Unknown case-distinct metadata keys remain independent; exact duplicate keys are still rejected at every depth. Custom unmarshalers remain opaque: callers must supply a method-free schema to inspect their fields.

func FoldName 

func FoldName(name string) string

FoldName folds a JSON name the same way encoding/json matches struct fields.

func FoldRune 

func FoldRune(r rune) rune

FoldRune returns the smallest rune in r's simple case-folding orbit.

func ObjectFields 

func ObjectFields(target reflect.Type) (map[string]reflect.Type, bool)

ObjectFields returns the fields encoding/json decodes an object into, keyed by their folded JSON name.
