Struct devices::virtio::video::decoder::backend::vaapi::BufferMapping

struct BufferMapping<'a, T: AsBufferHandle> {
    resource: &'a T,
    mapping: MemoryMappingArena,
}

A convenience type implementing persistent slice access for BufferHandles.

Fields

resource: &'a T

The underlying resource. Must be kept so as not to drop the BufferHandle

mapping: MemoryMappingArena

The mapping that backs the underlying slices returned by AsRef and AsMut

Implementations

impl<'a, T: AsBufferHandle> BufferMapping<'a, T>

pub fn new(resource: &'a T, offset: usize, size: usize) -> Result<Self>

Creates a new BufferMap

Trait Implementations

impl<T: AsBufferHandle> AsMut<[u8]> for BufferMapping<'_, T>

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl<T: AsBufferHandle> AsRef<[u8]> for BufferMapping<'_, T>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.
