Announce std::simd is on nightly

Not 100% sure if this should go on the main blog or Inside Rust.

Please support non-2^N SIMD lane counts

The silicon that supports these more or less directly: GPUs handle Vec3s (`f32x3` typically) all the time already. Arm SVE supports 384-bit width vector registers and is available Soon™. RISCVV...

Minimizing dependencies

Hello, I have been trying to reduce the number of dependencies for rustc, because while it is natural to expect something like rustc to have a big download and compile,...

0.7.5 release appears to still depend on bare-metal 0.2.5

3

Unfortunately the recent 0.7.5 release was cut from the staging branch. https://github.com/rust-embedded/cortex-m/blob/e0bfe3ae21903e9dbd80e903e726f7341662e12b/Cargo.toml#L14-L22 Thus, it did not include recent dependency updates that are present on other branches, like the bump of...

Any resource of any considerable length or value inevitably hits this point of recursion: it must instruct the user on how to use it. Thanks to the excellent work of...

Incorrect size assumptions in `Array::as_slice()` mean it must be destroyed

4

Arrays currently can be converted into `&[T]` using `as_slice`, but in actuality their repr is boxed in a `usize`. Thus for types which are smaller than the machine's pointer width,...

`impl {TryFrom,From}<Datum>` for types which `impl FromDatum`

2

Currently, we have a FromDatum trait which represents extracting a type from the Postgres Datum representation, which was useful, partly because of the type safety complications about doing that for...

These files use `*mut` to some `T` when they could probably actually use either: - `NonNull` - `&T` - `&mut T` - `Option` - `Option` - `Option` The `Option`al forms...

These files use `*const` to some `T` when they could probably actually use either: - `NonNull` - `&T` - `Option` - `Option` The `Option`al forms of these types should be...

Deref impls to `time::*` may cause API instability

1

Exposing `impl Deref` is an extreme compatibility hazard in the future if those types change, as it means PGX's stability becomes "married" to that other crate. It's more typical for...
