In another, the function may be + * directly invoked on host data. + * + * Even when working strictly with host memory, it is often necessary to + * ensure that the data are in a particular layout for efficient access (e.g. + * column major vs row major) or that the the data are of a particular type + * (e.g. double) even though we wish to call the function with data of + * another compatible type (e.g. float). + * + * `mdbuffer` is a tool for ensuring that the data are represented in exactly + * the desired format and location while flexibly supporting data which may + * not already be in that format or location. It does so by providing a + * non-owning view on data which are already in the required form, but it + * allocates (owned) memory and performs a copy if and only if it is + * necessary. + * + * Usage example: + * @code{.cpp} + * template + * void foo_device(raft::resources const& res, mdspan_type data) { + * auto buf = raft::mdbuffer{res, raft::mdbuffer{data}, raft::memory_type::device}; + * // Data in buf is now guaranteed to be accessible from device. + * // If it was already accessible from device, no copy was performed. If it + * // was not, a copy was performed. + * + * some_kernel<<<...>>>(buf.view()); + * + * // It is sometimes useful to know whether or not a copy was performed to + * // e.g. determine whether the transformed data should be copied back to its original + * // location. This can be checked via the `is_owning()` method. + * if (buf.is_owning()) { + * raft::copy(res, data, buf.view()); + * } + * } + * @endcode + * + * Note that in this example, the `foo_device` template can be correctly + * instantiated for both host and device mdspans. Similarly we can use + * `mdbuffer` to coerce data to a particular memory layout and data-type, as in + * the following example: + * @code{.cpp} + * template + * void foo_device(raft::resources const& res, mdspan_type data) { + * auto buf = raft::mdbuffer, raft::row_major>{res, + * raft::mdbuffer{data}, raft::memory_type::device}; + * // Data in buf is now guaranteed to be accessible from device, and + * // represented by floats in row-major order. + * + * some_kernel<<<...>>>(buf.view()); + * + * // The same check can be used to determine whether or not a copy was + * // required, regardless of the cause. I.e. if the data were already on + * // device but in column-major order, the is_owning() method would still + * // return true because new storage needed to be allocated. + * if (buf.is_owning()) { + * raft::copy(res, data, buf.view()); + * } + * } + * @endcode + * + * Note that in this example, the `foo_device` template can accept data of + * any float-convertible type in any layout and of any memory type and coerce + * it to the desired device-accessible representation. + * + * Because `mdspan` types can be implicitly converted to `mdbuffer`, it is even + * possible to avoid multiple template instantiations by directly accepting an + * `mdbuffer` as argument, as in the following example: + * @code{.cpp} + * void foo_device(raft::resources const& res, raft::mdbuffer> data) + * { auto buf = raft::mdbuffer{res, data, raft::memory_type::device}; + * // Data in buf is now guaranteed to be accessible from device. + * + * some_kernel<<<...>>>(buf.view()); + * } + * @endcode + * + * In this example, `foo_device` can now accept any row-major mdspan of floats + * regardless of memory type without requiring separate template instantiations + * for each type. + * + * While the view method takes an optional compile-time memory type parameter, + * omitting this parameter will return a std::variant of mdspan types. This + * allows for straightforward runtime dispatching based on the memory type + * using std::visit, as in the following example: + * + * @code{.cpp} + * void foo(raft::resources const& res, raft::mdbuffer> data) { + * std::visit([](auto&& view) { + * // Do something with the view, including (possibly) dispatching based on + * // whether it is a host, device, managed, or pinned mdspan + * }, data.view()); + * } + * @endcode + * + * @tparam ElementType element type stored in the buffer + * @tparam Extents specifies the number of dimensions and their sizes + * @tparam LayoutPolicy specifies how data should be laid out in memory + * @tparam ContainerPolicy specifies how data should be allocated if necessary + * and how it should be accessed.

For instance, if a functor has been + * implemented with an operator that accepts only a `device_mdspan`, input data + * can be passed to that functor with minimal copies or allocations by wrapping + * the functor in this template. + * + * More specifically, host memory data will be copied to device before being + * passed to the functor as a `device_mdspan`. Device, managed, and pinned data + * will be passed directly to the functor as a `device_mdspan`. + * + * If the functor's operator were _also_ specialized for `host_mdspan`, then + * this wrapper would pass an input `host_mdspan` directly to the corresponding + * specialization. + * + * If a functor explicitly specializes for managed/pinned memory and receives + * managed/pinned input, the corresponding specialization will be invoked. If the functor does not + * specialize for either, it will preferentially invoke the device + * specialization if available and then the host specialization. Managed input + * will never be dispatched to an explicit specialization for pinned memory and + * vice versa. + * + * Dispatching is performed by coercing the input mdspan to an mdbuffer of the + * correct type.
