* vulkano: instance: derive Ord, PartialOrd for PhysicalDeviceType Useful for want differeniating integrated and discrete GPUs in a hash table. * vulkano: don't pull in all of crossbeam Just pull in crossbeam-queue, since that's what used. Having a smaller set of packages is easier for system integrators such as myself. * vulkano: memory: add import support, separate device memory and mappings, and much more! - Chaining structs copied shamelessly and poorly from Ash :-) - Import support, as previously promised. - DeviceMemoryMappings so we can maybe one day expose the binding model. - Attempts to rigorously check Valid Usage IDs (VUIDs). A note about error handling: - Currently, Vulkano error handling is a bit unclear. For example, I didn't define a "DeviceMemoryMappingError" and simply reused the "DeviceMemoryAllocError" already present in the file. In reality, both a theoretical "DeviceMemoryMappingError" and the already present "DeviceMemoryAllocError" should mostly just check the valid usage IDs present in the Vulkan spec (or return an error from the implementation). This code pattern is common throughout Vulkano. Perhaps we should go to a simpler VulkanoResult<T>??? Just an idea. - Also, is Vulkano a validation layer??? LunarG tracks every single VUIDs in their uber layer already: https://www.lunarg.com/wp-content/uploads/2019/04/UberLayer_V3.pdf Of course, given how Vulkan drivers are relatively straigtforward compared to OpenGL, it's generally possible to match LunarG *using Rust* if we just have a big enough community. Whether we want to or not may be up for debate. For now, I just followed the original vision of tomaka and added validation. If we do want to do it, then we have to be more rigorous about it. |

Examples
These examples use unreleased functionality of vulkano. For a snapshot of the examples at the latest vulkano release take a look at the examples repository
Running the examples:
cargo run --bin <example>
Example:
cargo run --bin triangle
If you want to compare performances with other libraries, you should pass the --release flag as
well. Rust is pretty slow in debug mode.
