If the end result is that no action is accepted,\nthe drag source will receive wl_data_source.cancelled.\n\nThe dnd_actions argument must contain only values expressed in the\nwl_data_device_manager.dnd_actions enum, and the preferred_action\nargument must only contain one of those values set, otherwise it\nwill result in a protocol error.\n\nWhile managing an \"ask\" action, the destination drag-and-drop client\nmay perform further wl_data_offer.receive requests, and is expected\nto perform one last wl_data_offer.set_actions request with a preferred\naction other than \"ask\" (and optionally wl_data_offer.accept) before\nrequesting wl_data_offer.finish, in order to convey the action selected\nby the user. If the preferred action is not in the\nwl_data_offer.source_actions mask, an error will be raised.\n\nIf the \"ask\" action is dismissed (e.g. user cancellation), the client\nis expected to perform wl_data_offer.destroy right away.\n\nThis request can only be made on drag-and-drop offers, a protocol error\nwill be raised otherwise.\n\nOnly available since version 3 of the interface"]

The chosen\naction may change alongside negotiation (e.g. an \"ask\" action can turn\ninto a \"move\" operation), so the effects of the final action must\nalways be applied in wl_data_offer.dnd_finished.\n\nClients can trigger cursor surface changes from this point, so\nthey reflect the current action.\n\nOnly available since version 3 of the interface"]

#[doc = "an onscreen surface\n\nA surface is a rectangular area that may be displayed on zero\nor more outputs, and shown any number of times at the compositor's\ndiscretion. They can present wl_buffers, receive user input, and\ndefine a local coordinate system.\n\nThe size of a surface (and relative positions on it) is described\nin surface-local coordinates, which may differ from the buffer\ncoordinates of the pixel content, in case a buffer_transform\nor a buffer_scale is used.\n\nA surface without a \"role\" is fairly useless: a compositor does\nnot know where, when or how to present it. The role is the\npurpose of a wl_surface. Examples of roles are a cursor for a\npointer (as set by wl_pointer.set_cursor), a drag icon\n(wl_data_device.start_drag), a sub-surface\n(wl_subcompositor.get_subsurface), and a window as defined by a\nshell protocol (e.g. wl_shell.get_shell_surface).\n\nA surface can have only one role at a time. Initially a\nwl_surface does not have a role. Once a wl_surface is given a\nrole, it is set permanently for the whole lifetime of the\nwl_surface object. Giving the current role again is allowed,\nunless explicitly forbidden by the relevant interface\nspecification.\n\nSurface roles are given by requests in other interfaces such as\nwl_pointer.set_cursor. The request should explicitly mention\nthat this request gives a role to a wl_surface. Often, this\nrequest also creates a new protocol object that represents the\nrole and adds additional functionality to wl_surface. When a\nclient wants to destroy a wl_surface, they must destroy this 'role\nobject' before the wl_surface.\n\nDestroying the role object does not remove the role from the\nwl_surface, but it may stop the wl_surface from \"playing the role\".\nFor instance, if a wl_subsurface object is destroyed, the wl_surface\nit was created for will be unmapped and forget its position and\nz-order. It is allowed to create a wl_subsurface for the same\nwl_surface again, but it is not allowed to use the wl_surface as\na cursor (cursor is a different role than sub-surface, and role\nswitching is not allowed)."]

This means that at commit time the supplied\nbuffer size must be an integer multiple of the buffer_scale. If\nthat's not the case, an invalid_size error is sent.\n\nThe x and y arguments specify the location of the new pending\nbuffer's upper left corner, relative to the current buffer's upper\nleft corner, in surface-local coordinates. In other words, the\nx and y, combined with the new surface size define in which\ndirections the surface's size changes. Setting anything other than 0\nas x and y arguments is discouraged, and should instead be replaced\nwith using the separate wl_surface.offset request.\n\nWhen the bound wl_surface version is 5 or higher, passing any\nnon-zero x or y is a protocol violation, and will result in an\n'invalid_offset' error being raised. To achieve equivalent semantics,\nuse wl_surface.offset.\n\nSurface contents are double-buffered state, see wl_surface.commit.\n\nThe initial surface contents are void; there is no content.\nwl_surface.attach assigns the given wl_buffer as the pending\nwl_buffer. wl_surface.commit makes the pending wl_buffer the new\nsurface contents, and the size of the surface becomes the size\ncalculated from the wl_buffer, as described above. After commit,\nthere is no pending buffer until the next attach.\n\nCommitting a pending wl_buffer allows the compositor to read the\npixels in the wl_buffer. The compositor may access the pixels at\nany time after the wl_surface.commit request. When the compositor\nwill not access the pixels anymore, it will send the\nwl_buffer.release event. Only after receiving wl_buffer.release,\nthe client may reuse the wl_buffer. A wl_buffer that has been\nattached and then replaced by another attach instead of committed\nwill not receive a release event, and is not used by the\ncompositor.\n\nIf a pending wl_buffer has been committed to more than one wl_surface,\nthe delivery of wl_buffer.release events becomes undefined. A well\nbehaved client should not rely on wl_buffer.release events in this\ncase. Alternatively, a client could create multiple wl_buffer objects\nfrom the same backing storage or use wp_linux_buffer_release.\n\nDestroying the wl_buffer after wl_buffer.release does not change\nthe surface contents. Destroying the wl_buffer before wl_buffer.release\nis allowed as long as the underlying buffer storage isn't re-used (this\ncan happen e.g. on client process termination). However, if the client\ndestroys the wl_buffer before receiving the wl_buffer.release event and\nmutates the underlying buffer storage, the surface contents become\nundefined immediately.\n\nIf wl_surface.attach is sent with a NULL wl_buffer, the\nfollowing wl_surface.commit will remove the surface content."]

A compositor can decide to only\nadvertise the current mode and never send other modes. Clients\nshould not rely on non-current modes.\n\nThe size of a mode is given in physical hardware units of\nthe output device. This is not necessarily the same as\nthe output size in the global compositor space. For instance,\nthe output may be scaled, as described in wl_output.scale,\nor transformed, as described in wl_output.transform. Clients\nwilling to retrieve the output size in the global compositor\nspace should use xdg_output.logical_size instead.\n\nThe vertical refresh rate can be set to zero if it doesn't make\nsense for this output (e.g. for virtual outputs).\n\nThe mode event will be followed by a done event (starting from\nversion 2).\n\nClients should not use the refresh rate to schedule frames. Instead,\nthey should use the wl_surface.frame event or the presentation-time\nprotocol.\n\nNote: this information is not always meaningful for all outputs. Some\ncompositors, such as those exposing virtual outputs, might fake the\nrefresh rate or the size."]

It may be sent after\nbinding the output object or if the output scale changes\nlater. If it is not sent, the client should assume a\nscale of 1.\n\nA scale larger than 1 means that the compositor will\nautomatically scale surface buffers by this amount\nwhen rendering. This is used for very high resolution\ndisplays where applications rendering at the native\nresolution would be too small to be legible.\n\nIt is intended that scaling aware clients track the\ncurrent output of a surface, and if it is on a scaled\noutput it should use wl_surface.set_buffer_scale with\nthe scale of the output. That way the compositor can\navoid scaling the surface, and the client can supply\na higher detail image.\n\nThe scale event will be followed by a done event.\n\nOnly available since version 2 of the interface"]

The name is only\nguaranteed to be unique for the compositor instance.\n\nThe same output name is used for all clients for a given wl_output\nglobal. Thus, the name can be shared across processes to refer to a\nspecific wl_output global.\n\nThe name is not guaranteed to be persistent across sessions, thus cannot\nbe used to reliably identify an output in e.g. configuration files.\n\nExamples of names include 'HDMI-A-1', 'WL-1', 'X11-1', etc. However, do\nnot assume that the name is a reflection of an underlying DRM connector,\nX11 connection, etc.\n\nThe name event is sent after binding the output object. This event is\nonly sent once per output object, and the name does not change over the\nlifetime of the wl_output global.\n\nCompositors may re-use the same output name if the wl_output global is\ndestroyed and re-created later.

The description is not guaranteed to be unique among all\nwl_output globals.

#[doc = "sub-surface interface to a wl_surface\n\nAn additional interface to a wl_surface object, which has been\nmade a sub-surface. A sub-surface has one parent surface. A\nsub-surface's size and position are not limited to that of the parent.\nParticularly, a sub-surface is not automatically clipped to its\nparent's area.\n\nA sub-surface becomes mapped, when a non-NULL wl_buffer is applied\nand the parent surface is mapped. The order of which one happens\nfirst is irrelevant. A sub-surface is hidden if the parent becomes\nhidden, or if a NULL wl_buffer is applied. These rules apply\nrecursively through the tree of surfaces.\n\nThe behaviour of a wl_surface.commit request on a sub-surface\ndepends on the sub-surface's mode. The possible modes are\nsynchronized and desynchronized, see methods\nwl_subsurface.set_sync and wl_subsurface.set_desync. Synchronized\nmode caches the wl_surface state to be applied when the parent's\nstate gets applied, and desynchronized mode applies the pending\nwl_surface state directly. A sub-surface is initially in the\nsynchronized mode.\n\nSub-surfaces also have another kind of state, which is managed by\nwl_subsurface requests, as opposed to wl_surface requests. This\nstate includes the sub-surface position relative to the parent\nsurface (wl_subsurface.set_position), and the stacking order of\nthe parent and its sub-surfaces (wl_subsurface.place_above and\n.place_below). This state is applied when the parent surface's\nwl_surface state is applied, regardless of the sub-surface's mode.\nAs the exception, set_sync and set_desync are effective immediately.\n\nThe main surface can be thought to be always in desynchronized mode,\nsince it does not have a parent in the sub-surfaces sense.\n\nEven if a sub-surface is in desynchronized mode, it will behave as\nin synchronized mode, if its parent surface behaves as in\nsynchronized mode. This rule is applied recursively throughout the\ntree of surfaces. This means, that one can set a sub-surface into\nsynchronized mode, and then assume that all its child and grand-child\nsub-surfaces are synchronized, too, without explicitly setting them.\n\nIf the wl_surface associated with the wl_subsurface is destroyed, the\nwl_subsurface object becomes inert. Note, that destroying either object\ntakes effect immediately. If you need to synchronize the removal\nof a sub-surface to the parent surface update, unmap the sub-surface\nfirst by attaching a NULL wl_buffer, update parent, and then destroy\nthe sub-surface.\n\nIf the parent wl_surface object is destroyed, the sub-surface is\nunmapped."]
