Trait dencode::IterSink

pub trait IterSink<Item> {
    type Error;
    fn ready(&mut self) -> Result<(), Self::Error>;
    fn start_send(&mut self, item: Item) -> Result<(), Self::Error>;
    fn flush(&mut self) -> Result<(), Self::Error>;
}

An IterSink is a value into which other values can be sent.

Values are sent in two phases: first by internally buffering the value, and then actually writing the value upon flushing.

Associated Types

type Error

The type of value produced by the sink when an error occurs.

Required methods

fn ready(&mut self) -> Result<(), Self::Error>

Attempts to prepare the IterSink to receive a value, adjusting the internal buffer if necessary.

This method must be called prior to each call to start_send.

fn start_send(&mut self, item: Item) -> Result<(), Self::Error>

Write a value to the internal buffer. Each call to this function must be preceded by a successful call to ready.

fn flush(&mut self) -> Result<(), Self::Error>

Flush any remaining output from this sink’s internal buffer.
