Struct FetchCanceller

pub(crate) struct FetchCanceller {
    request_id: Option<RequestId>,
    core_resource_thread: Option<CoreResourceThread>,
}

RAII fetch canceller object. By default initialized to having a request associated with it, which can be manually cancelled with cancel, or automatically cancelled on drop. Calling ignore will sever the relationship with the request, meaning it cannot be cancelled through this canceller from that point on.

Fields

request_id: Option<RequestId>

core_resource_thread: Option<CoreResourceThread>

Implementations

impl FetchCanceller

pub(crate) fn new( request_id: RequestId, core_resource_thread: CoreResourceThread, ) -> Self

Create a FetchCanceller associated with a request,

pub(crate) fn cancel(&mut self)

Cancel a fetch if it is ongoing

pub(crate) fn ignore(&mut self)

Use this if you don’t want it to send a cancellation request on drop (e.g. if the fetch completes)
