Detailed Description

template<class Iterator>
class folly::gen::detail::RangeSource< Iterator >

RangeSource - For producing values from a folly::Range. Useful for referring to a slice of some container.

This type is primarily used through the 'from' function, like:

auto rangeSource = from(folly::range(v.begin(), v.end())); auto sum = rangeSource | sum;

Reminder: Be careful not to invalidate iterators when using ranges like this.
