A thin wrapper around a native Swift dictionary providing an efficient decoding interface for a JSON object.
@frozen struct ObjectDecoder<CodingKey> where CodingKey : Hashable, CodingKey : RawRepresentable, CodingKey : Sendable, CodingKey.RawValue == Stringimport JSONASTimport JSONDecoding@frozen struct JSONA container for some UTF-8 encoded JSON source text.
protocol Hashable : EquatableA type that can be hashed into a Hasher to produce an integer hash value.
protocol RawRepresentable<RawValue>A type that can be converted to and from an associated raw value.
protocol Sendableassociatedtype RawValueThe raw type that can be used to represent all values of the conforming type.
@frozen struct StringA Unicode string value that is a collection of characters.
protocol TraceableDecoderA type that represents a scope for decoding operations.
@frozen struct ArrayShapeAn efficient interface for checking the length of a decoded array at run time.
@frozen enum ArrayShapeCriteriaWhat shape you expected an array to have.
@frozen struct ArrayShapeErrorAn array had an invalid scheme.
@frozen struct DecodingError<Location> where Location : SendableAn error occurred while decoding a document field.
@frozen struct FieldDecoder<Key> where Key : Sendable@frozen enum ObjectKeyError<CodingKey> where CodingKey : SendableAn object had an invalid key scheme.
@frozen struct OptionalDecoder<Key> where Key : SendableA field that may or may not exist in a document. This type is the return value of ObjectDecoder’s non-optional subscript, and is useful for obtaining structured diagnostics for “key-not-found” scenarios.
@frozen enum SingleKeyError<CodingKey>@frozen struct ValueError<Value, Cases> where Value : SendableA decoder successfully to cast a variant to an expected value type, but it was not a valid case of the expected destination type.
init(_ index: [CodingKey : JSON.Node] = [:]) var index: [CodingKey : JSON.Node]protocol CopyableA type whose values can be implicitly or explicitly copied.
protocol Escapableprotocol JSONDecodableA type that can be decoded from a JSON variant value.
