Struct DeviceDescriptor 

#[non_exhaustive]
pub struct DeviceDescriptor {
    pub user_agent: String,
    pub viewport: DeviceViewport,
    pub screen: Option<DeviceViewport>,
    pub device_scale_factor: f64,
    pub is_mobile: bool,
    pub has_touch: bool,
    pub default_browser_type: String,
}

Describes a device for browser emulation.

Use with BrowserContext::new_context() options to emulate a specific device, matching the behavior of playwright.devices["iPhone 13"] in Python/JS.

Device descriptors are accessed by name from crate::protocol::Playwright::devices. The name is the map key, not a field of the descriptor itself.

Example

use playwright_rs::protocol::Playwright;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let playwright = Playwright::launch().await?;

    let iphone = &playwright.devices()["iPhone 13"];
    assert!(iphone.is_mobile);
    assert!(iphone.has_touch);
    assert_eq!(iphone.default_browser_type, "webkit");

    playwright.shutdown().await?;
    Ok(())
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

user_agent: String

The user-agent string for the device.

viewport: DeviceViewport

The viewport dimensions.

screen: Option<DeviceViewport>

The screen size the device reports through window.screen, larger than the viewport on a device whose browser chrome takes room. Pass it as BrowserContextOptions::screen to emulate the device fully. Not every descriptor has one.

device_scale_factor: f64

The device pixel ratio (e.g., 3.0 for Retina displays).

is_mobile: bool

Whether the device is a mobile device.

has_touch: bool

Whether the device supports touch input.

default_browser_type: String

The default browser type for the device: "chromium", "firefox", or "webkit".
