pub struct Context { /* private fields */ }
Expand description
A context bound to a fetch
event.
Implementations§
source§impl Context
impl Context
sourcepub fn new(inner: JsContext) -> Self
pub fn new(inner: JsContext) -> Self
Constructs a context from an underlying JavaScript context object.
sourcepub fn wait_until<F>(&self, future: F)where
F: Future<Output = ()> + 'static,
pub fn wait_until<F>(&self, future: F)where F: Future<Output = ()> + 'static,
Extends the lifetime of the “fetch” event which this context is bound to, until the given future has been completed. The future is executed before the handler terminates but does not block the response. For example, this is ideal for caching responses or handling logging.
context.wait_until(async move {
let _ = cache.put(request, response).await;
});
sourcepub fn pass_through_on_exception(&self)
pub fn pass_through_on_exception(&self)
Prevents a runtime error response when the Worker script throws an unhandled exception. Instead, the script will “fail open”, which will proxy the request to the origin server as though the Worker was never invoked.
