Struct DmaBufPlane 

pub struct DmaBufPlane {
    pub fd: Arc<OwnedFd>,
    pub offset: u64,
    pub stride: u32,
}

One plane of a dma-buf: a descriptor, its offset into the buffer, and its row stride.

The descriptor is shared (Arc) so a handle clones without duplicating descriptors: the producer keeps its own reference, and the renderer duplicates in the kernel when it imports.

Fields

fd: Arc<OwnedFd>

The plane’s file descriptor.

offset: u64

The plane’s offset within the buffer, in bytes.

stride: u32

The plane’s row stride, in bytes.

Implementations

impl DmaBufPlane

pub fn new(fd: OwnedFd, offset: u64, stride: u32) -> Self

A plane from an owned descriptor, its byte offset within the buffer, and its row stride.
