The syntax here seems to have gone awry, I think the match block is missing the closing } and there's an extra ) in the match clause.
Additionally, {:} is equivalent to {}, so feel free to leave out the colon.

This example doesn't compile:
exampel.rs:6:20: 6:46 error: the impl referenced by this path needs 2 type parameters, but 0 type parameters were supplied
exampel.rs:6 let mut artists = TreeMap::new::<uint, ~str>();
^~~~~~~~~~~~~~~~~~~~~~~~~~
exampel.rs:24:44: 24:48 error: mismatched types: expected `&uint` but found `<generic integer #4>` (expected &-ptr but found integral variable)
exampel.rs:24 for (year, artist) in artists.upper_bound(1980) {
^~~~
(and that's after I fixed the aritst typo below.)
I think the make check-stage1-doc-crate-collections target will run all the examples here and show you any errors that occur. (Once you've done that once, you can use make check-stage1-doc-crate-collections NO_REBUILD=1 as you update to just run the tests straight away, rather than doing a bootstrap.)

Run stable `fmt` & `cargo` through `rustup` `cargo test -p ide-assists` fails on Windows/x64/nightly: ```shell > rustup self update info: checking for self-updates rustup unchanged - 1.25.1 > rustup update info: syncing channel updates for 'stable-x86_64-pc-windows-msvc' info: syncing channel updates for 'nightly-x86_64-pc-windows-msvc' info: checking for self-updates stable-x86_64-pc-windows-msvc unchanged - rustc 1.62.1 (e092d0b 2022-07-16) nightly-x86_64-pc-windows-msvc unchanged - rustc 1.64.0-nightly (affe0d3 2022-08-05) info: cleaning up downloads & tmp directories > rustup show Default host: x86_64-pc-windows-msvc rustup home: C:\Users\stanc\.rustup installed toolchains -------------------- stable-x86_64-pc-windows-msvc nightly-x86_64-pc-windows-msvc (default) active toolchain ---------------- nightly-x86_64-pc-windows-msvc (default) rustc 1.64.0-nightly (affe0d3 2022-08-05) > cargo test -p ide-assists test tests::sourcegen::sourcegen_assists_docs ...

A simple `xshell` test failed too: ```rust use xshell::{cmd, Shell}; fn main() { let sh = &Shell::new().unwrap(); sh.set_var("RUSTUP_TOOLCHAIN", "stable"); let version = cmd!(sh, "rustfmt --version").read().unwrap_or_default(); println!("{version}"); } ``` Bypassing `xshell` and using `Command` directly failed too: ```rust use std::process::{Command, Stdio}; fn main() { let child = Command::new("rustfmt") .arg("--version") .stdin(Stdio::null()) .stdout(Stdio::piped()) .env("RUSTUP_TOOLCHAIN", "stable") .spawn() .expect("failed to start"); let output = child.wait_with_output().unwrap(); let version = String::from_utf8_lossy(&output.stdout); println!("{version}"); } ``` Spawning `cargo +stable fmt version` [failed too](rust-lang/rustup#3036) with `error: no such subcommand: +stable`. Only `rustup run stable` worked fine for both `cargo` and `fmt`. Thanks to `@lnicola` for a live investigation session, hints and tips.
