    // Provided methods

        self,
        complete_cb: FComplete,

Expand description

The extension trait that adds .on_complete(...) and .on_cancellation(...) to all Streams.

To use it, do: use ogre_stream_ext::StreamExtFinalizationCallbacks; use futures::StreamExt; // if you also want .map(), .filter(), etc.

Then: mystream .map(|x| …) .on_complete(|| println!(“done!”)) .on_cancellation(|| println!(“cancelled early!”))

Provided Methods§

Source

fn on_complete<FComplete>( self, complete_cb: FComplete, ) -> StreamWithFinalizationCallbacks<Self, FComplete, impl FnOnce()>
where FComplete: FnOnce(),

Source

fn on_cancellation<FCancel>( self, cancel_cb: FCancel, ) -> StreamWithFinalizationCallbacks<Self, impl FnOnce(), FCancel>
where FCancel: FnOnce(),

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.
