# GaugeStyle

Defines the implementation of all gauge instances within a view hierarchy.

## Declaration

```swift
@MainActor @preconcurrency protocol GaugeStyle
```

## Overview

Overview To configure the style for all the Gauge instances in a view hierarchy, use the gaugeStyle(_:) modifier. For example, you can configure a gauge to use the circular style: Gauge(value: batteryLevel, in: 0...100) {     Text("Battery Level") } .gaugeStyle(.circular) A type conforming to this protocol inherits @preconcurrency @MainActor isolation from the protocol if the conformance is included in the type’s base declaration: struct MyCustomType: Transition {     // `@preconcurrency @MainActor` isolation by default } Isolation to the main actor is the default, but it’s not required. Declare the conformance in an extension to opt out of main actor isolation: extension MyCustomType: Transition {     // `nonisolated` by default }
