Struct v4l::io::dmabuf::arena::EntryDmaBufProtected

pub struct EntryDmaBufProtected {
    id: *mut DmaBuf,
    buf: Option<ArcRwLockWriteGuard<RawRwLock, DmaBuf>>,
}

Fields

id: *mut DmaBuf

This serves as a stable identifier of a buffer corresponding to this slot, meaning a buffer with this ID has the same index known by the kernel and the same device.

buf: Option<ArcRwLockWriteGuard<RawRwLock, DmaBuf>>

The buffer which may be handed out to the user after it’s ready. RwLock locked for writing ensures no other reference can try to use it while it’s waiting to be filled.
