Fields

sync_mode: SyncMode

What synchronization requirements the backend has

pipeline_cache: bool

Whether the backend supports pipeline caches

kernel_lang: KernelTarget

What kernel langauge the backend takes

easily_update_bind_groups: bool

Whether the backend supports bind groups that are updated while commands are already recorded. This makes bind groups far cheaper to use

semaphore_signal: bool

Whether the backend supports CPU->GPU synchronization using CPU-side semaphore signalling.

map_buffers: bool

Whether the backend supports directly mapping host memory on the CPU instead of just reads/writes. This is likely false only on some wgpu backends such as WebGPU itself. Currently it is true everywhere.

is_unified_memory: bool

Whether the system has unified memory, which provides opportunities for optimization, particularly on apple, mobile, or other devices with integrated GPUs

map_buffer_while_gpu_use: bool

Whether you can map buffers while they are in use on the GPU(even if the slices don’t overlap)

upload_download_buffers: bool

Whether it supports dual upload-download buffers
