vk::load

A Vulkan driver failure or a missing command (entry, instance or device level).

Owned snapshot of the API version and extension names used at creation. Device snapshots inherit instance extensions and cap the API version by the selected physical device. Feature records are owned; no input pNext pointers are retained.

Version/extension admission for one exact command spelling. This does not validate enabled feature bits, parameters or Vulkan valid usage.

A native object returned successfully before dispatch initialization failed.

Global dispatch. Instances created here retain the native library independently.

Enumerate instance extensions available without any layer.

Enumerate all implicit and explicit Vulkan layers installed on this system.

Query the loader API version. A Vulkan 1.0 loader has no version command.

Snapshot of exact feature records used to create a device.

One explicitly captured native feature member. Names use the registry’s C spelling, so shaderInt64 remains recognizable in specification diagnostics.

Retains a created handle and its library when automatic rollback is impossible. The native object still needs explicit cleanup; dropping this error performs no destruction. Keep its parent and original allocator callback state alive.

Loading or required-command resolution failure.
