Worker

Struct Worker 

Source
pub struct Worker {
    inner: Weak<Worker>,
}
Expand description

The Worker class represents a WebWorker. worker event is emitted on the page object to signal a worker creation. close event is emitted on the worker object when the worker is gone.

page.on('worker', worker => {
 console.log('Worker created: ' + worker.url());
 worker.on('close', worker => console.log('Worker destroyed: ' + worker.url()));
});

console.log('Current workers:');
for (const worker of page.workers())
 console.log('  ' + worker.url());

impl Clone for Worker

Source§

fn clone(&self) -> Worker

Returns a duplicate of the value. Read more
1.0.0 · Source§

Source§

impl PartialEq for Worker

Source§

fn eq(&self, other: &Self) -> bool
