Trait IterSinkExt 

pub trait IterSinkExt<Item>: IterSink<Item> {
    // Provided methods
    fn send(&mut self, item: Item) -> Result<(), Self::Error> { ... }
    fn send_all<I>(&mut self, items: I) -> Result<(), Self::Error>
       where I: IntoIterator<Item = Result<Item, Self::Error>> { ... }
}

An extension trait for IterSinks that provides a few convenient functions.

Provided Methods

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

Fully processed an item into the sink, including flushing.

Note that, because of the flushing requirement, it is usually better to batch together items to send via send_all, rather than flushing between each item.

fn send_all<I>(&mut self, items: I) -> Result<(), Self::Error>

where I: IntoIterator<Item = Result<Item, Self::Error>>,

Fully process the iterator of items into the sink, including flushing.

This will drive the iterator to keep producing items until it is exhausted, sending each item to the sink. It will complete once both the input iterator is exhausted, and the sink has received and flushed all items.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
