Promotes a nil result to a thrown TypecastError.
func cast<T>(with cast: (`Self`) throws -> T?) throws -> T A TypecastError if the given curried method returns nil.
If T conforms to BSONDecodable, prefer calling its throwing init(bson:) to calling this method directly.
import BSONABIModels the BSON type system and the binary interface of the BSON serialization format.
@frozen enum AnyValueAny BSON value.
@frozen enum BSONThe namespace for all BSON types.
@frozen struct TypecastError<Value>A decoder failed to cast a variant to an expected value type.
protocol BSONDecodableA type that can be decoded from a BSON variant value backed by some type of storage not particular to the decoded type.
init(bson: BSON.AnyValue) throws Attempts to cast a BSON variant backed by some storage type to an instance of this type. The implementation can copy the contents of the backing storage if needed.
init(arrayLiteral: `Self`...) init(booleanLiteral: Bool) init(dictionaryLiteral: (BSON.Key, `Self`)...) init(floatLiteral: Double) init(integerLiteral: Int) Creates an instance initialized to the specified integer value. It will be an int32(_:) value if it fits, otherwise it will be an int64(_:).
init(stringLiteral: String) var binary: BSON.BinaryView<ArraySlice<UInt8>>? { get }Attempts to unwrap a binary array from this variant.
var document: BSON.Document? { get }Attempts to unwrap a document from this variant.
var list: BSON.List? { get }Attempts to unwrap a list from this variant.
var size: Int { get }The size of this variant value when encoded.
var type: BSON.AnyType { get }The type of this variant value.
var utf8: BSON.UTF8View<ArraySlice<UInt8>>? { get }Attempts to unwrap an instance of UTF8View from this variant. Its UTF-8 code units will not be validated, which allowes this method to return in constant time.
func `as`(_: UnixMillisecond.Type) -> UnixMillisecond? Attempts to load an instance of UnixMillisecond from this variant.
func `as`(_: BSON.Decimal128.Type) -> BSON.Decimal128? Attempts to load an instance of Decimal128 from this variant.
func `as`(_: BSON.Identifier.Type) -> BSON.Identifier? Attempts to load an instance of Identifier from this variant.
func `as`(_: BSON.Max.Type) -> BSON.Max? Attempts to load a max key from this variant.
func `as`(_: BSON.Min.Type) -> BSON.Min? Attempts to load a min key from this variant.
func `as`(_: BSON.Null.Type) -> BSON.Null? Attempts to load an explicit null from this variant.
func `as`(_: BSON.Regex.Type) -> BSON.Regex? Attempts to load an instance of Regex from this variant.
func `as`(_: String.Type) -> String? Attempts to load an instance of String from this variant. Its UTF-8 code units will be validated (and repaired if needed).
func `as`(_: Bool.Type) -> Bool? Attempts to load an instance of Bool from this variant.
func `as`<Integer>(_: Integer.Type) throws -> Integer? where Integer : FixedWidthInteger Attempts to load an instance of some FixedWidthInteger from this variant.
func `as`<Fraction>(_: Fraction.Type) -> Fraction? where Fraction : BinaryFloatingPoint Attempts to load an instance of some BinaryFloatingPoint type from this variant.
