Struct BrowserPool 

pub struct BrowserPool { /* private fields */ }

Thread-safe pool of reusable BrowserInstances.

Maintains a warm set of idle browsers ready for immediate acquisition (<100ms), and lazily launches new instances when demand spikes.

Example

use stygian_browser::{BrowserConfig, BrowserPool};

let pool = BrowserPool::new(BrowserConfig::default()).await?;
let handle = pool.acquire().await?;
handle.release().await;

Implementations

impl BrowserPool

pub async fn new(config: BrowserConfig) -> Result<Arc<Self>>

Create a new pool and pre-warm config.pool.min_size browser instances.

Warmup failures are logged but not fatal — the pool will start smaller and grow lazily.

Example

use stygian_browser::{BrowserPool, BrowserConfig};

let pool = BrowserPool::new(BrowserConfig::default()).await?;

pub async fn acquire(self: &Arc<Self>) -> Result<BrowserHandle>

Acquire a browser handle from the pool.

• If a healthy idle browser is available it is returned immediately.
• If active < max_size a new browser is launched.
• Otherwise waits up to pool.acquire_timeout.

Errors

Returns BrowserError::PoolExhausted if no browser becomes available within pool.acquire_timeout.

Example

use stygian_browser::{BrowserPool, BrowserConfig};

let pool = BrowserPool::new(BrowserConfig::default()).await?;
let handle = pool.acquire().await?;
handle.release().await;

pub fn stats(&self) -> PoolStats

Snapshot of current pool metrics.

Example

use stygian_browser::{BrowserPool, BrowserConfig};

let pool = BrowserPool::new(BrowserConfig::default()).await?;
let s = pool.stats();
println!("active={} idle={} max={}", s.active, s.idle, s.max);
