Struct dma_boom::MappedDmaBufWo

pub struct MappedDmaBufWo<'a>(pub(crate) MappedDmaBuf<&'a mut DmaBuf>);

A write-only Dmabuf mapped in memory. The underlying data gets cache-synced on creation and destruction.

Tuple Fields

0: MappedDmaBuf<&'a mut DmaBuf>

Implementations

impl<'a> MappedDmaBufWo<'a>

pub(crate) fn new( buf: &'a mut DmaBuf, len: usize, mapping_ptr: *mut u8, ) -> Result<Self, MapError>

pub fn as_slice_mut(&mut self) -> &mut [u8]

Access the underlying data mutably.

Data in this struct is cache-coherently guarded only for write access, so reading may give unexpected results.
