Struct JsonLinesStream 

pub struct JsonLinesStream<R, T> { /* private fields */ }

Available on crate feature async only.

An asynchronous stream over the lines of an AsyncBufRead value R that decodes each line as JSON of type T.

This stream yields items of type Result<T, std::io::Error>. Errors occurr under the same conditions as for AsyncJsonLinesReader::read().

Streams of this type are returned by AsyncJsonLinesReader::read_all() and AsyncBufReadJsonLines::json_lines().

Trait Implementations

impl<R: Debug, T: Debug> Debug for JsonLinesStream<R, T>

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

Formats the value using the given formatter.

impl<R: AsyncBufRead, T> Stream for JsonLinesStream<R, T>

where T: DeserializeOwned,

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.

impl<'__pin, R, T> Unpin for JsonLinesStream<R, T>

where __Origin<'__pin, R, T>: Unpin,
