Construct a Logger given a label identifying the creator of the Logger.
init(label: String) An identifier for the creator of a Logger.
The label should identify the creator of the Logger. This can be an application, a sub-system, or even a datatype.
import LoggingA Logging API for Swift.
struct LoggerA Logger is the central type in SwiftLog. Its central function is to emit log messages using one of the methods corresponding to a log level.
@frozen struct StringA Unicode string value that is a collection of characters.
init(label: String, factory: (String) -> any LogHandler) Construct a Logger given a label identifying the creator of the Logger or a non-standard LogHandler.
init(label: String, factory: (String, Logger.MetadataProvider?) -> any LogHandler) Construct a Logger given a label identifying the creator of the Logger or a non-standard LogHandler.
init(label: String, metadataProvider: MetadataProvider) Construct a Logger given a label identifying the creator of the Logger and a non-standard MetadataProvider.
var handler: any LogHandler { get set }A computed property to access the LogHandler.
var label: String { get }var logLevel: Logger.Level { get set }Get or set the log level configured for this Logger.
var metadataProvider: Logger.MetadataProvider? { get }The metadata provider this logger was created with.
subscript(metadataKey metadataKey: String) -> Logger.Metadata.Value? { get set } Add, change, or remove a logging metadata item.

enum LevelThe log level.
struct MessageLogger.Message represents a log message’s text. It is usually created using string literals.
struct MetadataProviderA MetadataProvider is used to automatically inject runtime-generated metadata to all logs emitted by a logger.
enum MetadataValueA logging metadata value. Logger.MetadataValue is string, array, and dictionary literal convertible.
typealias Metadata = [String : MetadataValue]Metadata is a typealias for [String: Logger.MetadataValue] the type of the metadata storage.
