low
The low 32 bits of this identifier. The high byte of this integer is the byte at offset +8 of this identifier.
var low: UInt32 { get }The low 32 bits of this identifier. The high byte of this integer is the byte at offset +8 of this identifier.
var low: UInt32 { get }import BSONABIModels the BSON type system and the binary interface of the BSON serialization format.
@frozen struct IdentifierA MongoDB object reference. This type models a MongoDB ObjectId.
@frozen enum BSONThe namespace for all BSON types.
@frozen struct UInt32A 32-bit unsigned integer value type.
init(_ high: UInt32, _ middle: UInt32, _ low: UInt32) Creates an identifier with the given high-, middle-, and low-components. The components are interpreted by platform endianness; therefore the values stored into bitPattern may be different if the current host is not big-endian.
init(integerLiteral: StaticBigInt) init(timestamp: UInt32, seed: Seed, ordinal: Ordinal) init(with initialize: (_ memory: UnsafeMutableRawBufferPointer) throws -> ()) rethrows Creates an identifier by delegating to the closure to initialize raw memory. The buffer contains 12 bytes and will be interpreted as a 96-bit, big-endian integer.
let bitPattern: (UInt32, UInt32, UInt32)var description: String { get }var middle: UInt32 { get }The middle 32 bits of this identifier. The high byte of this integer is the byte at offset +4 of this identifier.
var ordinal: Ordinal { get }The last three bytes of this identifier. The first tuple element is the byte at offset +9 of this identifier.
var seed: Seed { get }The middle five bytes of this identifier. The first tuple element is the byte at offset +4 of this identifier.
var timestamp: UInt32 { get }The high 32 bits of this identifier. The high byte of this integer is the byte at offset +0 of this identifier.
static func < (lhs: `Self`, rhs: `Self`) -> Bool Compares the bytes of this identifier in lexicographical order. This is the same as performing a lexicographic numeric comparison on (timestamp, middle, low). Depending on platform endianness, this may be different from performing a lexicographic numeric comparison on bitPattern directly.
static func == (lhs: `Self`, rhs: `Self`) -> Bool func hash(into hasher: inout Hasher) Hashes the bytes of this identifier in the order they are stored in memory.
