Struct GpuBuffer 

pub struct GpuBuffer { /* private fields */ }

Wrapper around GPU buffer that can be real or mock.

Design Pattern: Opaque Wrapper

This type hides whether it contains a real wgpu::Buffer or a mock. Users hold owned GpuBuffer, which is cheap to clone (Arc inside).

Benefits

1. No lifetimes - users own the buffer
2. Can be mock or real without user knowing
3. Clone is cheap (Arc internally for real buffers)

Implementations

impl GpuBuffer

pub fn from_wgpu(buffer: Buffer) -> Self

Create from real WGPU buffer

pub fn as_wgpu(&self) -> &Buffer

Get the underlying wgpu::Buffer (if real)

Panics

Panics if this is a mock buffer (test code should never call this)

Trait Implementations

impl Clone for GpuBuffer

fn clone(&self) -> GpuBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuBuffer

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

Formats the value using the given formatter.
