Issue https://github.com/denoland/deno/issues/22222  This PR moves `runtime/permissions` code to a upstream crate called `deno_permissions`. The `deno_permissions::PermissionsContainer` is put into the OpState and can be used instead of the current trait-based permissions system. For this PR, I've migrated `deno_fetch` to the new crate but kept the rest of the trait-based system as a wrapper of `deno_permissions` crate. Doing the migration all at once is error prone and hard to review. Comparing incremental compile times for `ext/fetch` on Mac M1: | profile | `cargo build --bin deno` | `cargo plonk build --bin deno` | | --------- | ------------- | ------------------- | | `debug` | 20 s | 0.8s | | `release` | 4 mins 12 s | 1.4s | |

Deno
Deno
(/ˈdiːnoʊ/, pronounced
dee-no) is a JavaScript, TypeScript, and WebAssembly runtime with secure
defaults and a great developer experience. It's built on V8,
Rust, and Tokio.
Learn more about the Deno runtime in the documentation.
Installation
Install the Deno runtime on your system using one of the commands below. Note that there are a number of ways to install Deno - a comprehensive list of installation options can be found here.
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
Build and install from source
Complete instructions for building Deno from source can be found in the manual here.
Your first Deno program
Deno can be used for many different applications, but is most commonly used to
build web servers. Create a file called server.ts and include the following
TypeScript code:
Deno.serve((_req: Request) => {
return new Response("Hello, world!");
});
Run your server with the following command:
deno run --allow-net server.ts
This should start a local web server on http://localhost:8000.
Learn more about writing and running Deno programs in the docs.
