A rustlang adapter for readers which delegate read bytes to a writer, adapted from the standard library's
std::io::Read#tee which has since been deprecated.
rustdoc api documentation can be found here
The currently unstable/deprecated std library function looks like this
let tee_reader = reader.tee;
In broadcast this looks like
let tee_reader = new;
