Struct Streamer 

Source 
pub struct Streamer<'a> { /* private fields */ }
Expand description

Implements pagination on top of a SnapshotReceiver channel.

Implementations§

Source§

impl<'a> Streamer<'a>

Source

pub fn new(dest: &'a mut SnapshotReceiverProxy) -> Streamer<'a>

Prepares to send a snapshot over the given channel.

Takes a mutable reference to be sure that nobody else can write into the channel at the same time.

Source

pub async fn push_element(self, elem: SnapshotElement) -> Result<Self, Error>

Sends the given elem.

This method internally flushes the outgoing buffer, if necessary, so that it never exceeds the maximum allowed size.

Source

pub async fn end_of_snapshot(self) -> Result<(), Error>

Sends the end-of-snapshot marker.
