Code formatting for Rust Workers examples is off

[samscott89]

Example URL(s)

https://developers.cloudflare.com/workers/examples/websockets/

Actual Behavior

This is the example from that page:

use worker::\*;

#[event(fetch)]
async fn fetch(req: HttpRequest, \_env: Env, \_ctx: Context) -> Result<worker::Response> {
let upgrade_header = match req.headers().get("Upgrade") {
Some(h) => h.to_str().unwrap(),
None => "",
};
if upgrade_header != "websocket" {
return worker::Response::error("Expected Upgrade: websocket", 426);
}
}

Issues:

• Glob import has been escaped worker::\*
• Variable underscore also has been escaped: \_env
• Indentation all gone

Expected Behavior

It was correct prior to #21258

Additional information

Doing a git blame it looks like these were probably the result of an over-eager autoformatter in this PR:

#21258

Opened a PR to fix the specific issues.

FYI it's currently the case that anyone with the Prettier extension installed could easily end up making unexpectedly large changes. For example, I run prettier on all the workers examples, there are a lot of changes:

❯ npx prettier --write src/content/docs/workers/examples/*.mdx
...
❯ git diff --stat
 ...
 27 files changed, 748 insertions(+), 750 deletions(-)

It might be worth ignoring all *.mdx files in the .prettierignore if the intention isn't to have those be automatically formatted. But at least the changes in #23650 means that prettier no longer will mangle the current samples. e.g. see this comment: https://github.com/cloudflare/cloudflare-docs/pull/23650/files#r2205937078

Fixed in #23650
