Re-implements https://github.com/gfx-rs/wgpu/pull/4886 (CC @Wumpf)
without the `document-features` crate, which has issues integrating into
Firefox builds after being `cargo vendor`ed into its repository. This
issue is being tracked against
https://github.com/slint-ui/document-features/issues/20. Once resolved,
I expect that we will want to revert this PR in its entirety, since
`document-features` is still a good addition to `wgpu`'s documentation
story.
Internally, consensus has already been achieved for this change.
Firefox's ability to build unfortunately take priority over this
particular convenience. Hopefully, we won't have to compromise shortly!
I tested this by ensuring that the HTML output of our existing
`document_features::document_features!(…)` usage was exactly the same.
There should be exactly zero regressions in the current state of
documentation for users. For maintainers, I have added a disclaimer that
one needs to keep changes in sync. with the relevant `Cargo.toml`
manifests.
* Ensure device lost closure is called exactly once before being dropped.
This requires a change to the Rust callback signature, which is now Fn
instead of FnOnce. When the Rust callback or the C closure are dropped,
they will panic if they haven't been called. `device_drop` is changed
to call the closure with a message of "Device dropped." A test is added.
* Remove some locks in BindGroup
These are only written to clear the vectors when triaging bindgroups for destruction, which is not necessary. We can let the reference counts drop when the bind group is dropped.
* Make the mem_leak test pass again
We allocate a String every time we want to get a label for logging. The string is also allocated when logging is disabled. Either way, the allocation is unnecessary. This commit replaces the String with a dyn Debug reference which does not need any allocation.
* Remove the abstractions in resource maps
ResourceMaps had a rather convoluted system for erasing types that isn't needed anywhere except in one place in the triage_resource function. Everywhere else we are always dealing with specific types so using a member of the resource maps is simpler than going through an abstraction. More importantly there was a constraint that all contents of the resource maps implement the Resource trait which got in the way of some of the ongoing buffer snatching changes.
This commit simplifies this by removing the abstraction. Each resource type has its hash map directly in ResourceMaps and it is easier to have different requirements and behaviors depending on the type of the each resource.
* Introduce `dx12` and `metal` crate features to `wgpu`
* Implement dummy `Context` to allow compilation with `--no-default-features`
* Address review
* Remove `dummy::Context` in favor of `hal::api::Empty`
* Add changelog entry
* Panic early in `Instance::new()` if no backend is enabled

The general idea is to register postpone reigistering the buffer until towards the end of the function so that our unique reference to it lets us easily snatch the raw buffer if an error happens.
* Downgrade resource lifetime management log level to trace.
Allow promoting it back to info via an feature flag.
* Don't filter out info and warning log in the examples.
* Changelog entry.
* Downgrade storage log level from info to trace
* Downgrade tracking log level from info to trace
* Demote present log from info to debug
* Downgrade device/life.rs log from info to debug and trace
* Downgrade more log from info to trace
* Conditionally lift API logging from trace to info level
Most of this logging used to be info level until I demoted it to trace. Unfortunately this gets in my way because:
- Most of the logging I currently need is these API entry points, there is is a fair amount of more verbose logging in wgpu at higher levels than trace
- Firefox disable all trace and debug logging for optimized builds, which means I miss the this API logging where I need most.
This patch lifts the api logging back to info level.
* Move the api logging behind the api_log macro
* Clean up the trace-level logging for devices
* Log the descriptors for create_buffer and create_texture.
* Make logged ids more concise
Logged ids go from 'Id { index: 204, epoch: 1, backend: Vulkan }' to 'Id(204,1,vk)'.
* Log errors in more places.
Let `naga::TypeInner::Matrix` hold a full `Scalar`, with a kind and
byte width, not merely a byte width, to make it possible to represent
matrices of AbstractFloats for WGSL.
