pub struct Streamed<Op: Operation> { /* private fields */ }Expand description
One reply as it arrives: its events, and the fold that has seen each of
them. It is what Model::stream returns for
every operation, and what a call finishes.
An error is the last item: the stream ends after it. Stop polling to pause; drop the stream to cancel.
Implementations§
Source§impl<Op: Operation> Streamed<Op>
impl<Op: Operation> Streamed<Op>
Sourcepub async fn finish(self) -> Result<Op::Response, ProviderError>
pub async fn finish(self) -> Result<Op::Response, ProviderError>
Read the rest of the reply, then fold it with the provider’s end into
the response: what Model::call returns for
the same reply. An error the stream yielded, now or before, is the
result; a reply the provider did not end is
ProviderError::Truncated.
Source§impl Streamed<Completion>
impl Streamed<Completion>
Sourcepub fn relay(label: impl Into<String>, events: StreamEvents) -> Self
pub fn relay(label: impl Into<String>, events: StreamEvents) -> Self
A stream relayed over the bus under label: its events, then the
response the origin folded. A relay that ends without one was cut
short.
Sourcepub fn into_relay(self) -> StreamEvents
pub fn into_relay(self) -> StreamEvents
This stream as the bus carries it: its items, then the response it folds into, or the error that ended it. A reply cut short closes the relay without a response, as its transport closed.
Sourcepub fn partial(&self) -> CompletionResponse
pub fn partial(&self) -> CompletionResponse
What arrived so far: every part that ended, and the provider’s end once it arrived. Valid after an error, and after the caller stopped polling.
