Struct fastly::handle::PendingRequestHandle

#[repr(transparent)]
pub struct PendingRequestHandle { /* private fields */ }

A handle to a pending asynchronous request returned by RequestHandle::send_async() or RequestHandle::send_async_streaming().

A handle can be evaluated using PendingRequestHandle::poll(), PendingRequestHandle::wait(), or select_handles(). It can also be discarded if the request was sent for effects it might have, and the response is unimportant.

Implementations

impl PendingRequestHandle

pub fn as_u32(&self) -> u32

Get the underlying representation of the handle.

This should only be used when calling the raw ABI directly, and care should be taken not to reuse or alias handle values.

pub fn poll(self) -> PollHandleResult

Try to get the result of a pending request without blocking.

This function returns immediately with a PollHandleResult; if you want to block until a result is ready, use wait().

pub fn wait(self) -> Result<(ResponseHandle, BodyHandle), SendErrorCause>

Block until the result of a pending request is ready.

If you want check whether the result is ready without blocking, use poll().

Trait Implementations

impl Debug for PendingRequestHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<PendingRequest> for PendingRequestHandle

fn from(pr: PendingRequest) -> Self

Converts to this type from the input type.

impl Hash for PendingRequestHandle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl PartialEq<PendingRequestHandle> for PendingRequestHandle

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

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
