An error that is thrown when a key cannot be mapped to a keyspace.
@frozen struct KeyspaceErrorNormally, the library ignores unrecognized document keys, in order to facilitate schema evolution. However, when using documents to represent arbitrary associative mappings, such as Dictionary, it is often preferable to fail decoding instead of silently dropping items.
import BSONABIModels the BSON type system and the binary interface of the BSON serialization format.
import BSONDecodingImplements the BSON decoding system.
@frozen enum BSONThe namespace for all BSON types.
@frozen struct Dictionary<Key, Value> where Key : HashableA collection whose elements are key-value pairs.
protocol TracingDecoderA type that represents a scope for decoding operations.
@frozen struct BinaryDecoder@frozen struct BinaryTypecastErrorA list had an invalid number of elements.
@frozen struct DecodingError<Location> where Location : SendableAn error occurred while decoding a document field.
@frozen struct DocumentDecoder<CodingKey> where CodingKey : Hashable, CodingKey : RawRepresentable, CodingKey : Sendable, CodingKey.RawValue == StringA thin wrapper around a native Swift dictionary providing an efficient decoding interface for a Document.
@frozen enum DocumentKeyError<Key> where Key : SendableA document had an invalid key scheme.
@frozen struct FieldAccessor<Key> where Key : SendableA field that may or may not exist in a document. This type is the return value of DocumentDecoder’s non-optional subscript, and is useful for obtaining structured diagnostics for “key-not-found” scenarios.
@frozen struct FieldDecoder<Key> where Key : SendableA field that is already known to exist in a document. This type is the return value of DocumentDecoder’s optional subscript.
@frozen struct KeyspaceDecoder<Key>@frozen struct ListDecoderAn iterable type that produces this list’s elements, with associated indices. Parsing a list is slightly faster than parsing a general Document, because this method ignores the document keys.
@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.
protocol CopyableA type whose values can be implicitly or explicitly copied.
protocol EquatableA type that can be compared for value equality.
protocol Error : SendableA type representing an error value that can be thrown.

import BSONAn umbrella module providing a BSON parser, encoder, and decoder.
protocol CustomStringConvertibleA type with a customized textual representation.
