Detailed Description

template<typename C>
struct jh::ranges::to_fn< C >

Function object implementing jh::ranges::to.

Provides both direct-call and pipe-style interfaces for constructing a closable container from a compatible range.

Direct form

auto dq = jh::ranges::to<std::deque<int>>(v);

Pipe form

auto dq = v | jh::ranges::to<std::deque<int>>();

With extra arguments

std::pmr::monotonic_buffer_resource pool;
auto pmr_vec = v | jh::ranges::to<std::pmr::vector<int>>(std::pmr::polymorphic_allocator<int>(&pool));

The adaptor supports additional constructor arguments for allocator- or parameterized container types and automatically deduces the correct construction path.

Template Parameters

C	The target container type.
