Struct FetchCanceller 

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

Fetch canceller object. By default initialized to having a request associated with it, which can be aborted or terminated. 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>

keep_alive: bool

Implementations

impl FetchCanceller

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

Create a FetchCanceller associated with a request, and a particular(public vs private) resource thread.

pub(crate) fn keep_alive(&self) -> bool

fn cancel(&mut self)

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)
