Struct vk_alloc::Allocation

pub struct Allocation<LT: Lifetime> {
    pub device_memory: DeviceMemory,
    pub offset: DeviceSize,
    pub size: DeviceSize,
    // some fields omitted
}

An allocation of the Allocator.

Fields

device_memory: DeviceMemory

The DeviceMemory of the allocation. Managed by the allocator.

offset: DeviceSize

The offset inside the DeviceMemory.

size: DeviceSize

The size of the allocation.

Implementations

impl<LT: Lifetime> Allocation<LT>

pub fn mapped_slice(&self) -> Result<Option<&[u8]>, AllocatorError>

Returns a valid mapped slice if the memory is host visible, otherwise it will return None. The slice already references the exact memory region of the sub allocation, so no offset needs to be applied.

pub fn mapped_slice_mut(&mut self) -> Result<Option<&mut [u8]>, AllocatorError>

Returns a valid mapped mutable slice if the memory is host visible, otherwise it will return None. The slice already references the exact memory region of the sub allocation, so no offset needs to be applied.

Trait Implementations

impl<LT: Clone + Lifetime> Clone for Allocation<LT>

fn clone(&self) -> Allocation<LT>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<LT: Debug + Lifetime> Debug for Allocation<LT>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<LT: Lifetime> Send for Allocation<LT>

impl<LT: Lifetime> Sync for Allocation<LT>
