Implement Eq/PartialEq, Hash and Clone for Backtrace?

1

When building things like built-in memory profilers and similar, it's quite useful to be able to deduplicate captured callstacks without having to resolve them - since resolving stack traces can...

Separate license check for [dev-dependencies] vs [dependencies]

1

Sometimes, it might be interesting to use libraries with release-incompatible licenses in `[dev-dependencies]`. One example would be `dssim`, which is licensed under AGPL, and can be useful for comparing graphical...

I and some others have been porting a body of HLSL code to rust-gpu. Here's some notes about unexpected differences, pitfalls, and hard-to-port things. ### Fixable issues (doesn't mean they're...

For loops need more optimizations

2

Due to how for loops over a range work in Rust, a lot of scaffolding code is generated that is then expected to be optimized away, but in rust-gpu, that...

Pass constants into #[spirv(compute(threads(...)))] ?

6

Quite often, an algorithm will have a working data size configurable by a constant, and this size is correlated with the thread group size. Here's what I would like to...

The Vec3/Vec3A byte size conundrum

6

So, we currently have the Vec3 and Vec3A types from glam available. Vec3 is simply three scalar float32 values, and Vec3A is a SIMD type where an actual vector with...

Vulkan captures are not portable cross-vendor

7

Here's a straightforward dump, taken on Windows: http://www.ppsspp.org/unofficial/burnout.rdc I've sent it to someone using RenderDoc on Linux, and it crashes trying to load it. Is cross platform dump compatibility expected?

Delete README.md in the old repro and add a link to this one?

I googled "cargo apk" and ended up on the archived repository https://github.com/rust-windowing/android-rs-glue . Since so much of it still looks ok, I failed to noticed that it was archived, and...

GlobalProfiler::lock().new_frame() can be very expensive due to compression

1

Here's a small cutout from a Superluminal profile of an app that uses puffin scopes quite extensively:  The `pack()` call here takes around 1ms. Looks like the `pack()` call...

Don't merge scopes that have non-matching dynamic data

1

Scopes can have dynamic data, like this: ```rust puffin::profile_scope!("my_scope_id", my_dynamic_data); ``` However, puffin's UI still happily merges blocks with different dynamic data together if merging is enabled. It would be...
