Struct RequestStreamTyped 

pub struct RequestStreamTyped<Req> { /* private fields */ }

Typed counterpart of RequestStream for the flattened API. Yields Req (both Init and Data collapse to a bare Req); EOF when the substrate stream closes (REQUEST_END or CANCEL).

Decode failure terminates the stream with a single Err(RpcError::Codec) then closes — mirror of RpcStreamTyped’s contract on the response side.

For callers that need to distinguish “first request from this upload session” from “subsequent chunks” (sessions with explicit init handshake, rolling-window aggregation, etc.), call Self::into_chunked to get a ChunkedRequestStream<Req> instead.

Bidi streaming plan (Phase E).

Implementations

impl<Req> RequestStreamTyped<Req>

pub fn into_chunked(self) -> ChunkedRequestStream<Req>

Convert this flattened stream into a ChunkedRequestStream<Req> that distinguishes Chunk::Init from Chunk::Data. Same underlying substrate stream — no extra wire traffic, no replay.

seen_first is carried over from the source: if this handle has already yielded at least one item, the next chunk from the converted stream is Chunk::Data, not Chunk::Init.

Trait Implementations

impl<Req: DeserializeOwned + Unpin> Stream for RequestStreamTyped<Req>

type Item = Result<Req, RpcError>

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
