Struct ZwpLinuxBufferParamsV1

pub struct ZwpLinuxBufferParamsV1;

parameters for creating a dmabuf-based wl_buffer

This temporary object is a collection of dmabufs and other parameters that together form a single logical buffer. The temporary object may eventually create one wl_buffer unless cancelled by destroying it before requesting ‘create’.

Single-planar formats only require one dmabuf, however multi-planar formats may require more than one dmabuf. For all formats, an ‘add’ request must be called once per plane (even if the underlying dmabuf fd is identical).

You must use consecutive plane indices (‘plane_idx’ argument for ‘add’) from zero to the number of planes used by the drm_fourcc format code. All planes required by the format must be given exactly once, but can be given in any order. Each plane index can be set only once.
