[−][src]Crate stream_map_any
Allow merging async Streams of different output type.
It's very similar to Tokio's StreamMap
, except that it doesn't require the streams to have the
same output type.
This can be usefull when you don't know what type of streams should be combined, acting as a
runtime dynamic select.
Not a zero-cost-abstraction
Since we don't know what types of outputs the streams will generate, the generated output will
be a StreamMapAnyVariant
, a newtype around Box<dyn Any>
. As a result, we rely on dynamic
dispatching to transform it back into the desired output.
Benching shows that it's 2x as slow as a StreamMap
or a select
macro implementation.
