Struct PlatformGraphicsExternalImageDmaBufProperties 

pub struct PlatformGraphicsExternalImageDmaBufProperties {
    pub drm_format: u32,
    pub drm_modifier: u64,
    pub plane_count: i32,
    pub plane_fds: Option<Vec<i32>>,
    pub plane_strides: Option<Vec<u32>>,
    pub plane_offsets: Option<Vec<u32>>,
}

Describes the DRM layout of a dma-buf image.

Fields

drm_format: u32

The DRM_FORMAT_* fourcc of the buffer.

drm_modifier: u64

The DRM_FORMAT_MOD_* layout modifier of the buffer, or DRM_MODIFIER_INVALID for the implicit layout.

plane_count: i32

The number of memory planes. When zero, a single plane described by the handle itself and PlatformGraphicsExternalImageProperties::memory_offset is assumed.

plane_fds: Option<Vec<i32>>

Per-plane dma-buf file descriptors. When None, the handle’s file descriptor is used for every plane.

plane_strides: Option<Vec<u32>>

Per-plane row pitches in bytes.

plane_offsets: Option<Vec<u32>>

Per-plane byte offsets into the corresponding file descriptor.

Implementations
