[−][src]Struct tokio_serde_json::ReadJson
Adapts a stream of JSON encoded buffers to a stream of values by deserializing them.
ReadJson implements Sink by polling the inner buffer stream and
deserializing the buffer as JSON. It expects that each yielded buffer
represents a single JSON value and does not contain any extra trailing
bytes.
If a ReadJson is used concurrently from two or more threads, it is
guaranteed that only one object will be read at a time. In other words, once
an object begins being read, that object will continue being read until it
finishes or errors, and another object will only be read once the first
object completes.
Methods
impl<T, U> ReadJson<T, U>[src]
pub fn new(inner: T) -> Self[src]
Creates a new ReadJson with the given buffer stream.
pub fn get_ref(&self) -> &T[src]
Returns a reference to the underlying stream wrapped by ReadJson.
Note that care should be taken to not tamper with the underlying stream of data coming in as it may corrupt the stream of frames otherwise being worked with.
pub fn get_mut(&mut self) -> &mut T[src]
Returns a mutable reference to the underlying stream wrapped by
ReadJson.
Note that care should be taken to not tamper with the underlying stream of data coming in as it may corrupt the stream of frames otherwise being worked with.
pub fn into_inner(self) -> T[src]
Consumes the ReadJson, returning its underlying stream.
Note that care should be taken to not tamper with the underlying stream of data coming in as it may corrupt the stream of frames otherwise being worked with.
