import CoreMetrics

A Metrics API package for Swift.

final class Timer

A timer collects observations within a time window (usually things like request durations) and provides aggregated information about the data sample, for example, min, max and various quantiles. It is similar to a Recorder but specialized for values that represent durations.

@frozen struct String

A Unicode string value that is a collection of characters.

convenience init(label: String, dimensions: [(String, String)] = [])

Create a new Timer.

init(label: String, dimensions: [(String, String)], handler: TimerHandler)

Alternative way to create a new Timer, while providing an explicit TimerHandler.

convenience init(label: String, dimensions: [(String, String)] = [], preferredDisplayUnit displayUnit: TimeUnit)

Create a new Timer.

let _handler: TimerHandler

_handler is only public to allow access from MetricsTestKit. Do not consider it part of the public API.

var description: String { get }

let dimensions: [(String, String)]

func destroy()

Signal the underlying metrics library that this timer will never be updated again. In response the library MAY decide to eagerly release any resources held by this Timer.

func recordMicroseconds<DataType>(_ duration: DataType) where DataType : BinaryFloatingPoint

func recordMilliseconds<DataType>(_ duration: DataType) where DataType : BinaryFloatingPoint

Record a duration in milliseconds.

func recordMilliseconds<DataType>(_ duration: DataType) where DataType : BinaryInteger

Record a duration in milliseconds.

func recordNanoseconds(_ duration: Int64)

Record a duration in nanoseconds.

func recordNanoseconds<DataType>(_ duration: DataType) where DataType : BinaryInteger
