label

import CoreMetrics

A Metrics API package for Swift.

class Recorder

A recorder collects observations within a time window (usually things like response sizes) and can provide aggregated information about the data sample, for example, count, sum, min, max and various quantiles.

@frozen struct String

A Unicode string value that is a collection of characters.

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

Create a new Recorder.

init(label: String, dimensions: [(String, String)], aggregate: Bool, handler: RecorderHandler)

Alternative way to create a new Recorder, while providing an explicit RecorderHandler.

let _handler: RecorderHandler

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

let aggregate: Bool

var description: String { get }

let dimensions: [(String, String)]

func destroy()

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

func record<DataType>(_ value: DataType) where DataType : BinaryFloatingPoint

Record a value.

func record<DataType>(_ value: DataType) where DataType : BinaryInteger

Record a value.
