```rust vec![0u8; 100000].iter().map(|&x| { x as u64 * x as u64 }).sum::(); ``` is essentially what I'd like to use this crate to SIMD-accelerate. The issue I'm bumping into is...

There's a race where one thread tries to overallocate: `self.remaining.fetch_sub(size, Ordering::Acquire) >= size` and correctly fails, but `self.remaining` has now wrapped, so another thread's attempt to overallocate (before the first...

Parameterize reading of rows with a type parameter, checked against the schema, and used to specialize the deserialization of rows

### Proposal Parameterize reading (and potentially writing) of rows with a type parameter, which is checked against the file's schema, and used to specialize the deserialization (and potentially serialization) of...

Feature suggestion: assert_{lt,gt,le,ge}_size

2

This would be handy for example to ensure struct sizes don't grow beyond some limit. It can be implemented like this: ```rust macro_rules! assert_le_size { ($a:ty, $b:ty) => { const...

Match if author has admin or write permission on the repository

1

An attribute like `author_has_write`, a Boolean representing whether the PR author has `admin` or `write` permission on the repository, would I think solve my use case. --- **Use case:** I...

Clarify semantics of calling different poll_* methods from different tasks

2

How many `Waker`s should items implementing say `AsyncRead` and `AsyncWrite` have to store? At least some libs1 store two – a "read waker" and a "write waker". The former is...

StreamIds are allocated in the order in which they are polled, rather than the order of `open_uni`/`open_bi`

7

The docs specify incoming streams as being "in the order they were opened". Intuitively I'd expect this to be the order in which `open_uni`/`open_bi` were called, but it's actually the...

This enables big performance improvements by not having to clone elements for `ParallelStream`s. The complication is that, akin to [`crossbeam::scope`](https://docs.rs/crossbeam/0.7/crossbeam/fn.scope.html), we need to block before returning to avoid the user...

I've vendored what looks to me like a nice, well written, pure-Rust (but can optionally use OpenBLAS, Intel MKL, Netlib or Apple's Accelerate framework under the hood) [library](https://github.com/maciejkula/wyrm) that contains...
