Which Visual studio version does msvc toolset use?

If I have multiple Visual Studio versions installed (ex. 2019, 2017, 2015 or more...), which one will Rust's msvc toolset adopt?
Also, can I explicitly specify which version to use?

Maybe the 2019 version will be selected under the above conditions, is it correct?

It will choose the latest by default. You can get it to use another version by running rust in a "Native Tools Command Prompt". Check your start menu to find these.

@chrisd, thank you.

Is there any documentation that mentions it?
