Struct JsonStream 

pub struct JsonStream<C, B, T> { /* private fields */ }

An asynchronous JSON streamer for HTTP network requests.

Implementations

impl<C, B, T, D, E> JsonStream<C, B, T>

where C: Future<Output = Result<D, E>> + Unpin, D: Into<Response<B>>, B: Body + Unpin, T: DeserializeOwned, E: Error + 'static, B::Error: Error + 'static,

pub fn request(call: C, part: JsonPart) -> Self

Creates a new JSON streamer from the given HTTP response future.

Completes the request and streams the body for status 2XX responses.

Use JsonStream::process instead to customize response handling.

impl<B, T> JsonStream<Ready<Result<Response<B>, Infallible>>, B, T>

where B: Body + Unpin, T: DeserializeOwned, B::Error: Error + 'static,

pub fn process(resp: impl Into<Response<B>>, part: JsonPart) -> Self

Creates a new JSON streamer from the given HTTP response.

Trait Implementations

impl<C, B, T> Debug for JsonStream<C, B, T>

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

Formats the value using the given formatter.

impl<C, B, T, D, E> FusedStream for JsonStream<C, B, T>

where C: Future<Output = Result<D, E>> + Unpin, D: Into<Response<B>>, B: Body + Unpin, T: DeserializeOwned, E: Error + 'static, B::Error: Error + 'static,

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<C, B, T, D, E> Stream for JsonStream<C, B, T>

where C: Future<Output = Result<D, E>> + Unpin, D: Into<Response<B>>, B: Body + Unpin, T: DeserializeOwned, E: Error + 'static, B::Error: Error + 'static,

type Item = Result<T, Error>

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.
