Detailed Description

template<typename T1, typename T2>
class sensesp::Zip< T1, T2 >

Zip two producer values into a tuple.

Zips the connected producers' values into a tuple. The tuple is emitted once all producers have emitted a new value within max_age milliseconds. All producers must emit a new value before the next tuple is emitted.
