Struct DmaBufFormatCapability 

pub struct DmaBufFormatCapability {
    pub format: SurfaceFormatKind,
    pub modifiers: Vec<u64>,
}

One surface format, and every layout a renderer can import for it.

modifiers holds each DRM format modifier the importer will bind for this format, with DmaBufHandle::LINEAR present when a linear buffer is accepted. It is what a producer negotiates with: pass these to the allocator (VA-API’s VASurfaceAttribDRMFormatModifiers, a GBM allocator’s modifier list) so the buffer it makes is one the renderer can sample.

Fields

format: SurfaceFormatKind

The format.

modifiers: Vec<u64>

The modifiers accepted for it. Empty means the renderer cannot import the format at all.
