Struct BrowserPool 

pub struct BrowserPool { /* private fields */ }

A shared pool managing a single browser process with tab concurrency control.

The browser is lazily launched on the first acquire_browser() call. A semaphore limits the number of concurrent tabs to prevent memory exhaustion.

Implementations

impl BrowserPool

pub fn new(config: BrowserPoolConfig) -> Self

Creates a new browser pool with the given configuration.

pub fn available_tab_permits(&self) -> usize

Returns the number of tabs that may be opened immediately.

pub async fn warm_up(&self) -> UseResult<()>

Starts the configured provider without exposing its implementation handle.

pub async fn shutdown(&self)

Shuts down the browser and reaps its spawned child process.

Runtime ownership is detached into a cleanup task before this method awaits process termination. If the caller itself is cancelled, cleanup therefore continues instead of dropping Chrome’s parent and orphaning its renderer processes. Callers should release every Arc<Browser> returned by Self::acquire_browser first. If a shared handle remains, shutdown can request CDP close but final reaping is deferred until the last external handle is dropped.
