Struct DmaBufRingDescriptor

Namespace

Maplibre.NativeFfi

Assembly

Maplibre.NativeFfi.dll

A ring of dmabufs that the library allocates, for MapHandle.AttachDmaBufRing().

public readonly record struct DmaBufRingDescriptor : IEquatable<DmaBufRingDescriptor>

Implements

IEquatable<DmaBufRingDescriptor>

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

ValueType.ToString()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

Each buffer has the map's size in pixels and a format and modifier from formats. The library renders only DRM_FORMAT_ABGR8888 and DRM_FORMAT_ARGB8888. A modifier can give a buffer more planes than its format has, such as a plane of compression metadata, and the library takes any such modifier that its GPU can render into and share.

See mln_dma_buf_ring_descriptor in the C API reference.
