| [&lt;init&gt;](-init-.md) | `ServoEngine(defaultSettings: `[`DefaultSettings`](../../mozilla.components.concept.engine/-default-settings/index.md)` = DefaultSettings())`<br>Servo-based implementation of the Engine interface. |

### Properties

| Name | Summary |
|---|---|
| [settings](settings.md) | `val settings: `[`Settings`](../../mozilla.components.concept.engine/-settings/index.md)<br>See [Engine.settings](../../mozilla.components.concept.engine/-engine/settings.md) |
| [version](version.md) | `val version: `[`EngineVersion`](../../mozilla.components.concept.engine.utils/-engine-version/index.md)<br>Returns the version of the engine as [EngineVersion](../../mozilla.components.concept.engine.utils/-engine-version/index.md) object. |

### Functions

| Name | Summary |
|---|---|
| [createSession](create-session.md) | `fun createSession(private: `[`Boolean`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`): `[`EngineSession`](../../mozilla.components.concept.engine/-engine-session/index.md)<br>Creates a new engine session. |
| [createSessionState](create-session-state.md) | `fun createSessionState(json: <ERROR CLASS>): `[`EngineSessionState`](../../mozilla.components.concept.engine/-engine-session-state/index.md)<br>Create a new [EngineSessionState](../../mozilla.components.concept.engine/-engine-session-state/index.md) instance from the serialized JSON representation. |
