This allows `wgpu` to not unconditionally depend on `std::path::Path`. It’s also, in my opinion, more user-friendly, because the feature which most users will not use (and is not currently functional) is now a defaultable struct field instead of a required parameter. The disadvantage is that `wgpu-types` now has to know about tracing.
wgpu player
This is an application that allows replaying the wgpu workloads recorded elsewhere. It requires the player to be built from
the same revision as an application was linking to, or otherwise, the data may fail to load.
Launch as:
play <trace-dir>
When built with "winit" feature, it's able to replay the workloads that operate on a swapchain. It renders each frame sequentially and then waits for the user to close the window. When built without "winit", it launches in console mode and can replay any trace that doesn't use swapchains.
Note: replaying is currently restricted to the same backend as one used for recording a trace. It is straightforward, however, to just replace the backend in RON since it's serialized as plain text. Valid values are: Vulkan, Metal, and Dx12.
