class OwnedSpan

C++

template <typename T> class OwnedSpan

Owns a flat_buffer (via shared_ptr) and exposes a zero-copy span view. Used as the parameter type for 'out direct vector<T>' (primitive element) RPC arguments so the receive buffer is never copied.

include/nprpc/flat.hpp:652

Constructors

OwnedSpan<T>() = default

An empty span; valid() is false.

include/nprpc/flat.hpp:660

OwnedSpan<T>(std::shared_ptr< ::nprpc::flat_buffer> buf, Span<T> span) noexcept

Views span inside buf, keeping buf alive.

include/nprpc/flat.hpp:663

Methods

T *begin() const noexcept

First element.

include/nprpc/flat.hpp:675

std::shared_ptr< ::nprpc::flat_buffer> buffer() const noexcept

Keeps the underlying buffer alive (e.g. for async use after the RPC call).

include/nprpc/flat.hpp:688

T *data() const noexcept

First element.

include/nprpc/flat.hpp:671

T *end() const noexcept

One past the last element.

include/nprpc/flat.hpp:677

uint32_t size() const noexcept

Number of elements.

include/nprpc/flat.hpp:673

bool valid() const noexcept

Whether the span refers to a buffer.

include/nprpc/flat.hpp:685

Operators

operator Span<const T>() const noexcept

A non-owning read-only view of the same elements.

include/nprpc/flat.hpp:693

operator Span<T>() noexcept

A non-owning view of the same elements.

include/nprpc/flat.hpp:691

T &operator[](size_t i)

Element i.

include/nprpc/flat.hpp:680

const T &operator[](size_t i) const

Element i.
