fix(ops): disallow auto-borrowing OpState across potential await point (#16952)
Fixes https://github.com/denoland/deno/issues/16934

Example compiler error:
```
error: mutable opstate is not supported in async ops
   --> core/ops_builtin.rs:122:1
    |
122 | #[op]
    | ^^^^^
    |
    = note: this error originates in the attribute macro `op` (in Nightly builds, run with -Z macro-backtrace for more info)
```

Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.

Features

  • Secure by default. No file, network, or environment access, unless explicitly enabled.
  • Supports TypeScript out of the box.
  • Ships only a single executable file.
  • Built-in utilities.
  • Set of reviewed standard modules that are guaranteed to work with Deno.

Install

Shell (Mac, Linux):

curl -fsSL https://deno.land/install.sh | sh

PowerShell (Windows):

irm https://deno.land/install.ps1 | iex

Homebrew (Mac):

brew install deno

Chocolatey (Windows):

choco install deno

Scoop (Windows):

scoop install deno

Build and install from source using Cargo:

cargo install deno --locked

See deno_install and releases for other options.

Getting Started

Try running a simple program:

deno run https://deno.land/std/examples/welcome.ts

Or a more complex one:

const listener = Deno.listen({ port: 8000 });
console.log("http://localhost:8000/");

for await (const conn of listener) {
  serve(conn);
}

async function serve(conn: Deno.Conn) {
  for await (const { respondWith } of Deno.serveHttp(conn)) {
    respondWith(new Response("Hello world"));
  }
}

You can find a deeper introduction, examples, and environment setup guides in the manual.

The complete API reference is available at the runtime documentation.
