Detailed Description

template<class StorageType, class Container>
class folly::gen::detail::CopiedSource< StorageType, Container >

CopiedSource - For producing values from eagerly from a sequence of values whose storage is owned by this class. Useful for preparing a generator for use after a source collection will no longer be available, or for when the values are specified literally with an initializer list.

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

auto sourceCopy = fromCopy(makeAVector()); auto sum = sourceCopy | sum; auto max = sourceCopy | max;

Though it is also used for the initializer_list specialization of from().
