PendingRequestHandle

Struct PendingRequestHandle 

Source
pub struct PendingRequestHandle { /* private fields */ }
Expand description

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§

Source§

impl PendingRequestHandle

Source

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.

Source

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().

Source

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().
