* Mark EntryCustom::new_custom as unsafe
Passing a badly-behaved `load` function can invoke undefined behavior.
* Document required feature for Entry
* Support linking Vulkan directly
This is the preferred pattern in most environments when an application
cannot function without Vulkan, as it saves the libloading dependency,
eliminates an error case, and makes the Vulkan dependency visible to
the OS.
* Rename libloading feature to "loaded"
* Link by default
* Guide users towards linking the loader directly
* Remove unnecessary error type
InstanceError::LoadError was never constructed.
* Unify entry types
Simplifies the interface and allows a bunch of code to become
monomorphic.
* generator: Add edegecases for broken Video extension enum variants
* Replace deprecated `make_version()` with `make_api_version()`
* generator: Use the same predicate for push_next and its traits
Some structs turn out to be root structs when their name is not in the
`root_structs` set, even when they themselves extend another struct.
This was already taken care of for `push_next` which is emitted in this
situation, but the trait referenced by `push_next`'s `T` bound is still
relying on the `extends` field to not exist in `vk.xml` at all, leading
to it not being generated despite `push_next` needing it.
Fixes: 215511f ("Implement ExtendXXX for multiple root create infos if
there are more than 1")
* Update Vulkan-Headers to 12.175
* generator: Generate low-level structs with bindgen (for vk_video)
* Add ash-window as workspace member
* ash-window: fix repository link
* ash-window: Address CI fmt&clippy issues
* ash-window: Try fix SDL2 CI issues
* ash-window: Remove beryllium example
