<\/a>While working on a rust-based hackathon project at Qxf2<\/a>, I encountered an unresponsive function when creating new project in Rust.<\/p>\n

Being a newbie in rust, I was unable to figure out the cause. I tried looking up the internet but could not find any suitable solutions. Hence, I thought of documenting the resolution to this issue so that anyone hitting with same issue wouldn’t have to waste hours finding the cause.<\/p>\n

Problem<\/h4>\n

To begin with, I had to build a Rust function for AWS lambda. To do this, I first tried creating a project which would give me the default template with the following command.<\/p>\n

cargo lambda new rust_lambda<\/strong><\/p>\n

When you execute the command, you are shown the following in the terminal.<\/p>\n

\"\"<\/a><\/p>\n

\r\n? Is this function an HTTP function? (y\/N)\r\n[type `yes` if the Lambda function is triggered by an API Gateway, Amazon Load Balancer(ALB), or a Lambda URL]\r\n<\/pre>\n
In my case, the lambda function was not triggered with any of the above, so I chose ‘No’ and hit enter and got none in the response i.e. the cursor just stayed at the same place without giving me a success or any error message.<\/p>\n
The difficulty was not getting any error message and so, I was not sure why the command was not getting executed.<\/p>\n
\n
Root cause<\/h4>\n
I had to do trial and error before finding the root cause of the issue. It was the rust version. Sound simple, right? \ud83d\ude42 but this took a while. I was using rust 1.61.0 and updating it to the latest version helped resolve the issue. I would be happier if it were shown on the terminal but that gave me a way to dig deeper.<\/p>\n
\n
Solution<\/h4>\n
The next step was to update<\/a> the rustup which was the installer in my case with the following command:<\/p>\n
rustup update stable<\/strong><\/p>\n
Before Update<\/strong><\/p>\n
$ rustc –version
\nrustc 1.61.0 (fe5b13d68 2022-05-18)<\/p>\n
$ cargo –version
\ncargo 1.61.0 (a028ae42f 2022-04-29)<\/p>\n
After update<\/strong><\/p>\n
$ rustc –version
\nrustc 1.64.0 (a55dd71d5 2022-09-19)<\/p>\n
$ cargo –version
\ncargo 1.64.0 (387270bc7 2022-09-16)<\/p>\n
Once, the rust is updated to the newer version, you can again run the cargo lambda new command.<\/p>\n
\n
Conclusion<\/h4>\n
I have come across a few scenarios in Rust where the issues arise due to version incompatibility. Hence, It is better to have the updated version while working with rust projects.<\/p>\n","protected":false},"excerpt":{"rendered":"
