Detailed Description

template<class Value, class SequenceImpl>
class folly::gen::detail::Sequence< Value, SequenceImpl >

Sequence - For generating values from beginning value, incremented along the way with the ++ and += operators. Iteration may continue indefinitely. Value type specified explicitly.

This type is primarily used through the 'seq' and 'range' function, like:

int total = seq(1, 10) | sum; auto indexes = range(0, 10); auto endless = seq(0); // 0, 1, 2, 3, ...
