Unexplained print with partial valid rust-toolchain.toml

[Matthew-Chidlow]

Problem

When running commands like rustup show an unexplained message is printed to console:

Official(ToolchainDesc { channel: "stable", date: None, target: TargetTriple("x86_64-pc-windows-msvc") }) [Official(ToolchainDesc { channel: "stable", date: None, target: TargetTriple("x86_64-pc-windows-gnu") }), Official(ToolchainDesc { channel: "stable", date: None, target: TargetTriple("x86_64-pc-windows-msvc") }), Official(ToolchainDesc { channel:
"nightly", date: None, target: TargetTriple("x86_64-pc-windows-gnu") }), Official(ToolchainDesc { channel: "nightly", date: None, target: TargetTriple("x86_64-pc-windows-msvc") })]

This also happens when using cargo

Steps

1. Create a rust project
2. Add a rust-toolchain.toml file
3. Put in the file something like:

[toolchain]
channel = "stable-x86_64-pc-windows-msvc"

where the channel listed contains a host triple and is an installed toolchain

4. Try run almost any rustup or cargo command in the projects directory

Possible Solution(s)

I think the print is here:

rustup/src/config.rs

Line 594 in 1c612cf

eprintln!("{resolved_name:?} {ts:?}");

Probably should print some more context

@rbtcollins did you happen to forget deleting this after print debugging?

Can probably just do a PR for this, seems highly likely that that is the case.
