Struct Buffer 

pub struct Buffer {
    raw: Buffer,
    ownership: BufferOwnership,
}

Available on vulkan only.

Fields

raw: Buffer

ownership: BufferOwnership

Implementations

impl Buffer

pub unsafe fn from_raw(vk_buffer: Buffer) -> Self

Safety

• vk_buffer’s memory must be managed by the caller
• Externally imported buffers can’t be mapped by wgpu

pub unsafe fn from_raw_externally_owned( vk_buffer: Buffer, drop_callback: DropCallback, ) -> Self

Safety

• vk_buffer must outlive the returned Buffer.
• wgpu-hal will NOT call vkDestroyBuffer; the caller remains responsible for the buffer handle’s destruction. The drop_callback runs when the Buffer drops and may be used to release caller-side bookkeeping.
• Externally imported buffers can’t be mapped by wgpu.

pub unsafe fn from_raw_managed( vk_buffer: Buffer, memory: DeviceMemory, offset: u64, size: u64, ) -> Self

Safety

• We will use this buffer and the buffer’s backing memory range as if we have exclusive ownership over it, until the wgpu resource is dropped and the wgpu-hal object is cleaned up
• Externally imported buffers can’t be mapped by wgpu
• offset and size must be valid with the allocation of memory

pub unsafe fn raw_handle(&self) -> Buffer

Safety

• The buffer handle must not be manually destroyed
