Struct DeviceDescriptor 

pub struct DeviceDescriptor {
    pub user_agent: String,
    pub viewport: 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 [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

user_agent: String

The user-agent string for the device.

viewport: DeviceViewport

is_mobile: bool

Whether the device is a mobile device.

has_touch: bool

Whether the device supports touch input.

default_browser_type: String
