how to fix cargo build taking lot of time to install dependencies

There are several ways you can speed up the cargo build process and reduce the time it takes to install dependencies. Here are a few suggestions:

Use a Package Cache: One of the easiest ways to speed up the build process is to use a package cache. This will allow Cargo to reuse packages that have already been downloaded, rather than downloading them again for every build. You can enable the package cache by adding the --offline flag to your cargo build command.

Use a Dependency Manager: Another option is to use a dependency manager such as sccache or cargo vendor. These tools can help speed up the build process by caching and reusing compiled dependencies. sccache is a distributed cache that can be used to share compiled code between multiple machines, while cargo vendor allows you to bundle your dependencies with your project.

Optimize Build Settings: You can also optimize your build settings to reduce the amount of time it takes to compile your code. For example, you can use the --release flag to enable optimizations and generate smaller, faster binaries. You can also use the --jobs flag to specify the number of threads that Cargo should use when building your code.

Use a Faster Build System: Finally, you may want to consider using a faster build system such as Bazel or Ninja. These build systems can help speed up the build process by parallelizing the compilation of your code and optimizing the build process.

By following these tips, you should be able to significantly reduce the time it takes to install dependencies and build your code with Cargo.
