* vk/platform_types: Add `_screen_buffer` type for QNX
Ash doesn't implement `Drop` intentionally, to not be too opinionated
about holding (heap) references to their parent objects
(`Device`->`Instance`->`Entry`) and ensuring they are destroyed in the
right order. As such, reword the `create` documentation for `Instance`
and `Device` to mention their respective `destroy_*` function instead of
referring to them as being "droppable".
Note that `Entry` is droppable as it does not have a Vulkan `destroy`
function _and_ the dynamically loaded library (behind the "loaded"
feature) is kept alive only for the lifetime of `Entry`.

We don't mark any of the extern calls to Vulkan function-pointers safe
except for a few `Entry` functions. Their safety contract was easy to
validate, but now that we exposed a constructor function to let the user
provide function pointers in the form of `Entry::from_parts_1_1()` it is
no longer safe to assume that we are calling the function that adheres
to the contract specified in the Vulkan reference.
Because we don't rigorously do this validation and safe-marking anywhere
else either, mark these function calls as `unsafe`.

Generate templated builder setters for fields taking an `objecttype`
We already do this for hand-written extension functions but can now also
implement it for setters since `vk_parse` fields are available within
the builder generator code: when a field refers to another field for
setting its `objecttype`, that `VkObjectType` field setter is omitted
and instead assigned when the object is set, based on a type generic
that implements the `Handle` trait instead of an untyped `u64`.
These functions don't contribute anything and should be removed to clean
up the `features` and `extensions` files, while now also not showing in
the documentation anymore. The structs remain in place for associated
constants but are replaced with true unit-like structs (no curly
brackets anymore), and unneeded `unsafe impl Send/Sync` are removed as
well.
As these `load()` functions have been removed from the empty
feature-levels on `Entry` and `Device` as well, rather than
instantiating the unit structs and returning those the fields and
`fp_vX_X()` getters have been removed entirely.
Xlib defines `Display` as follows:
typedef struct _XDisplay Display;
And then always references this type as a pointer to it, e.g. `Display
*`. The same happens in `ash`, where `Display` is only ever referenced
as a raw pointer via `*mut Display`, so making `Display` itself a type
alias to `*mut c_void` is wrong and confusing. Switch it back to a
`c_void` to match the forward-declared (but otherwise undefined) `struct
_XDisplay`.
Looks like #630 typo'd the argument for `DeviceGroupCreation::new()` by
unnecessarily requiring a move (`Clone`) of `Entry` just to call
`get_instance_proc_addr()` on it. Replace this with a borrow to match
all other extensions.
* extensions/khr: Take the remaining `p_next`-containing structs as `&mut`
Version 2 of `get_physical_device_surface_capabilities` and the matching
`vk::SurfaceCapabilitiesKHR` struct exist solely to provide an `sType`
and `pNext` field to allow extending the original query with additional
data via extension structs. However, this API when introduced in #530
only returns the `default()`-initialized struct making it just as
constrained as `get_physical_device_surface_capabilities()`. Solve this
by taking `vk::SurfaceCapabilities2KHR` as `&mut` just like any similar
API.
And just like this, do the same for the remaining:
- `AccelerationStructure::get_acceleration_structure_build_sizes()`
- `ExternalMemoryFd::get_memory_fd_properties()`
- `ExternalMemoryWin32::get_memory_win32_handle_properties()`
In case these structs get extended somewhere down the line, which the
Vulkan API allows for.
* extensions/khr/acceleration_structure: Use `mem::zeroed()` in place of `vk::AccelerationStructureCompatibilityKHR::default()`
* Expose `FramebufferCreateInfo::attachment_count` builder for `IMAGELESS`
Don't omit the `attachment_count()` builder method, because it is valid
to set the number of attachments without providing attachments in the
`IMAGELESS` case.
Also change the generator array lookup to use the name of the count
field that is allowed to have a builder method, rather than the name of
the field that would use this as `len` field and hence cause it to be
skipped.
* Clean up clones
* README: Autoformat
* README: Remove deprecated `builder()` snippets and guidelines
#602 introduced builder functions directly on the raw Vulkan struct
types by using lifetime borrows which are FFI compatible (ABI is
identical) wuth raw pointers, simplifying the whole system and
protecting the user against losing lifetimes upon calling `.build()`.
However, this change wasn't propagated through to the `README` so the
code snippets were still showcasing removed `::builder()` and `.build()`
functions and documenting "the `.build()` footgun" which doesn't even
exist anymore 🎉
Some users are confused by seeing wildly different output after running
the generator, which is simply solved by running `rustfmt`. As this is
both confusing and "somewhat" slow, invoke `rustfmt` directly within the
generator by piping string contents through it before redirecting to
disk. This not only makes the output consistent, it is the fastest way
to reformat generator changes by omitting the round-trip to disk
entirely, nor having `rustfmt` recursively go through the workspace and
all files (including those that are not generated).
On a many-core machine these times are a bit skewed, but I want to
include them to prove the "speed" point nevertheless, even if simplicity
and consistency is the main reason to make this change:
Before:
time ./target/debug/generator && time cargo fmt --all
./target/debug/generator 3.51s user 1.25s system 99% cpu 4.769 total
cargo fmt --all 0.79s user 0.06s system 99% cpu 0.853 total
After:
time ./target/debug/generator
./target/debug/generator 4.51s user 0.41s system 99% cpu 4.931 total
There's no reason to use these steps anymore: besides being old,
unmaintained, and spitting out NodeJS deprecation warnings, GitHub's
`runner-images` come preloaded with all Rust tools and components we
need, and the syntax to run commands is more efficient, much shorter and
more apprehensible by simply matching what we'd use on our own
command-line, too.
Turns out we were doing the wrong thing for the right reason: the
`aliases` here aren't `vk.xml` aliases: they are renames. When
generating function pointers for extensions, a list of command
_definitions_ is collected, which can only ever be "root" `command`s.
Extensions typically reference stabilized `command`s under an alias with
the vendor tag suffixed, which the `Fn` struct field name is renamed to
using this `aliases` - now replaced with `rename_commands` - list, while
generating the rest of the "function pointer" command bits using the
"root" `command` (as this mostly pertains the parameters and return
type). With that explanation it becomes clear why
`generate_extension_commands()` was creating an "alias" mapping from
stabilized name to vendor-suffixed extension name, and calls
`generate_function_pointers()` with that mapping - and a list of
stabilized/root `command`s - rather than passing `cmd_aliases` directly.
(This `cmd_aliases` list exists because the rename always happens in the
root `<commands>` element: extensions then `<require>` the aliased
rather than the stabilized name, so the base for this alias is found
first to look up the base command, and then stored in `rename_commands`
to rename it back to the aliased name).
With improved clarity we can now also borrow the name strings rather
than cloning them in many places.
This helper function isn't consistently implemented across most
extension wrappers, and promotes bad Vulkan patterns by not making it
obvious to the caller that `get_physical_device_properties2()` can and
should be used to fill multiple properties structs at once.

For the upcoming `api` attribute in `vk.xml` commands also need to be
processed through `vk-parse` which has support for all the new
attributes, while `vkxml` is deprecated and completely untouched for
years. This conversion unfortunately requires whipping up yet another
quick-and-dirty `nom` parser of a specific subset of C used in `vk.xml`
to describe parameter signatures. This PR shows that conversion is
complete and provides no accidental semantic differences.
Also update `vk-parse` to `0.9` which contains a new `code` field on
`CommandParam` (`<param>` element) to be able to inspect the code
signature of individual parameters rather than parsing them out of (and
matching them back to `vk-parse`'s `params` array!) the `<command>`
/ `CommandDefinition` as a whole:

`CStr::from_bytes_with_nul_unchecked` is `const`-stable since Rust 1.59
which is already required for `ash` so it is high time to finally turn
these inlined `name()` functions into associated constants (which is a
breaking change in itself that cannot be backported).
`raw-window-handle 0.5.1` bumped from 1.60 to 1.64 in a
semver-compatible release, failing our CI infrastructure overnight.
Keep the `ash` version at `1.60` for now.
Commit c66db26 ("device: Replace `query_count` parameter in
`get_query_pool_results` with `data.len()` (#644)") removed this
parameter in favour of using `data.len()` to make it more obvious to use
an appropriate element type that matches the kind of request (see also
#639) so that the stride is filled in correctly, but it was not
mentioned in the changelog yet.
For upcoming `vk.xml` features (the new `api` attribute) some of our
codegen has to be converted to work on `vk-parse` types to make this
ergonomic (and there's a longstanding plan of factoring out `vkxml`
regardless). Start with converting the `#define` code and showcasing
that it does not affect the output (beyond removing the unneeded
edgecase for `VK_HEADER_VERSION` resulting in a doc link).
An upcoming extension will ship with an untyped `pCode` member (`void
*`) including a valid `len` field pointing to a `codeSize` field rather
than obscure Latex math and a `/4` expression in `altlen`. Limit the
scope of our workaround for that SPIR-V-specific `pCode` field to
`VkShaderModuleCreateInfo`.
Strangely some no-op cast remained in the codebase, and are only now
caught since Rust 1.66. In both cases the input value is already of the
correct type (independent of the platform).
Rustdoc since 1.66 points out that `<<ref>>` is malformed HTML, and the
resulting `<<devsandqueues-lost-device>>` isn't very helpful to users.
Convert it to the relevant link in both documentation and `Result`
`Display` to solve both issues at once.
