Struct EmulationController 

pub struct EmulationController { /* private fields */ }

Controller that exposes Emulation domain commands for a page.

Implementations

impl EmulationController

pub async fn apply_config(&self, config: &EmulationConfig) -> Result<()>

Applies a collection of emulation overrides to the target page.

Examples

let geolocation = Geolocation::new(37.7749, -122.4194).with_accuracy(1.0);
let config = EmulationConfig::default().with_geolocation(geolocation);
page.emulation().apply_config(&config).await?;

pub async fn set_geolocation(&self, geolocation: Geolocation) -> Result<()>

Overrides the page’s geolocation values until cleared.

pub async fn clear_geolocation(&self) -> Result<()>

Removes any geolocation override previously applied.

pub async fn set_timezone<T: Into<String>>(&self, timezone_id: T) -> Result<()>

Sets the emulated timezone identifier (IANA format).

pub async fn reset_timezone(&self) -> Result<()>

Resets the timezone override to the browser default.

pub async fn set_locale(&self, locale: Option<&str>) -> Result<()>

Overrides the page locale (for example “en-US”).

pub async fn set_media(&self, media: MediaEmulation) -> Result<()>

Applies media emulation settings, such as prefers-color-scheme.

pub async fn clear_media(&self) -> Result<()>

Clears any previously applied media emulation overrides.

pub async fn set_user_agent( &self, override_data: UserAgentOverride, ) -> Result<()>

Overrides the user agent string and optional metadata.
