Rust Raid is a repository for Rust learners and coding challenge seekers.

Note: In some linux distributions (specially WSL), the following packages might need to be installed to run some binaries that require network request.

1. pkg-config
2. libssl-dev

Example commands for installing in ubuntu

sudo apt install pkgconf
sudo apt install libssl-dev

You can check similar commands for other distributions

The repository contains the following:

• Algorithms that can be used to solve various problems.
• Examples of different design patterns and data structures.
• solutions to diverse challenges categorized by different topics(workspaces).
• advanced concepts that include memory management, multiprocessing, etc.
• Demo projects to polish your skills to the depth.

Each workspace contains multiple binaries so that it will be easier to run specific problem by selecting binaries.

You can run the cargo run --bin <binary_name> to run binaries.To run all test cases, you can run cargo test command, or to run specific test, you can run cargo test --bin <binary_name>

# Example: running binary for huffman encoding
cargo run --bin huffman
cargo test --bin huffman

Note: Topics that do not contain hyperlinks are work in progress and will be updated once the solution gets completed.

You can also create a PR with solution/enhancement to each topics.

Running binaries

To run any binary, you can run the command cargo run --bin <bin_name>

Example:

cargo run --bin practical_number

Note: Binary names might not always be the name of the file. Sometimes, a shorter version of the solution name is used to make easier to type. You can see the name of binary in the respective README.md file or the docstring of the respective solution. some examples of shorter version of solution name are as follows:

• The binary for huffman_coding.rs is just huffman.

Testing

There are test cases for each functions/challenges which will be beneficial for you to learn testing as well as test programs for errors.

To test programs, you can run cargo test command.

Example:

cargo test

# alternatively, to test individual binary, you can run
cargo test --bin your_program_name
