Implementations

impl ChromiumSetTab

pub async fn emulate_media( &self, media: Option<&str>, features: &[(&str, &str)], ) -> Result<()>

模拟媒体类型与特性(Emulation.setEmulatedMedia)。media 如 "print"/"screen"; features 如 [("prefers-color-scheme","dark")]。

pub async fn emulate_dark(&self, dark: bool) -> Result<()>

模拟深色 / 浅色模式(prefers-color-scheme)。

pub async fn offline(&self, on: bool) -> Result<()>

设置离线 / 在线(Network.emulateNetworkConditions)。

pub async fn network_conditions(&self, nc: &NetworkConditions) -> Result<()>

模拟网络条件(离线 / 限速)。

pub async fn cpu_throttling(&self, rate: f64) -> Result<()>

CPU 节流(Emulation.setCPUThrottlingRate)。rate=4.0 即降速到 1/4。

pub async fn grant_permissions( &self, origin: &str, permissions: &[&str], ) -> Result<()>

给某 origin 授予权限(Browser.grantPermissions),如 ["geolocation","clipboard-read","notifications","camera","microphone"]。

一把梭模拟设备(UA + 视口 + DPR + mobile + 触摸)。见 Device 预设。

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

清除设备模拟,恢复真实视口(Emulation.clearDeviceMetricsOverride)。

pub async fn local_storage_set(&self, key: &str, value: &str) -> Result<()>

写 localStorage(便捷,内部走 Runtime.evaluate)。

pub async fn local_storage_get(&self, key: &str) -> Result<Option<String>>

读 localStorage(不存在返回 None)。

pub async fn local_storage_remove(&self, key: &str) -> Result<()>

删 localStorage 项。

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

清空 localStorage。

pub async fn session_storage_set(&self, key: &str, value: &str) -> Result<()>

写 sessionStorage。

pub async fn session_storage_get(&self, key: &str) -> Result<Option<String>>

读 sessionStorage。

pub async fn session_storage_remove(&self, key: &str) -> Result<()>

删 sessionStorage 项。

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

清空 sessionStorage。

impl ChromiumSetTab

pub fn timeout(&self, d: Duration) -> &Self

设默认超时(影响 ele 等待 / 监听 / wait)。

pub async fn user_agent(&self, ua: &str) -> Result<()>

覆盖 User-Agent(Emulation.setUserAgentOverride)。

pub async fn cookies(&self, cookies: Vec<CookieParam>) -> Result<()>

批量设置 cookie。

pub fn window(&self) -> ChromiumWindow
