Description
Describe the bug
When I just quickly want to build some Rust code with older compilers, that no longer works:
<Compilation failed>
# For more information see the output window
# To open the output window, click or drag the "Output" icon at the bottom of this window
The output window says
error: argument for --edition must be one of: 2015|2018. (instead was `2021`)
Compiler returned: 1
Steps to reproduce
- visit https://rust.godbolt.org/
- select an old compiler (I used 1.37.0)
This leads to the error shown above.
Expected behavior
This should build successfully, as the given code is compatible with that compiler.
