I wanted to work on a Rust project and wanted to use IntelliJ and for this I installed Rust plugin:
https://plugins.jetbrains.com/plugin/8182-rust/docs/rust-quick-start.html
I then imported my project in IntelliJ, but somehow I'm not able to see the gutter menu next to my test case. I do not understand what I'm missing. I can see at the bottom in the Build window that there is something that fails.
Updating Workspace Info.
Execution failed (exit code 1).

stderr :
rustup show gave me the following:
Default host: x86_64-unknown-linux-gnu
rustup home: /opt/softwares/rustup
stable-x86_64-unknown-linux-gnu (default)
rustc 1.46.0 (04488afe3 2020-08-24)
Any ideas how to get this fixed?
I fixed it by opening the Rust project in IntelliJ, navigate to File -> Settings -> Rust and then set the Standard library to the following:
/opt/softwares/rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-unknown-linux-gnu/lib
That is the location where I installed the Rust Toolchain. Somehow Intellij was not picking it up and I had to set it manually.
