Release 202412040156

use unused graph struct

Release 202412021325

clean up using rust rover

somehow I can't build withing rust rover yet though

Release 202410281345

add graph

Sure, let's set up the graph implementation with tests. Here's how you can do it:

1. **Graph Implementation**:
   Define the graph structure and methods without a `main` function.

2. **Tests**:
   Add tests to verify the functionality of BFS and DFS.

Here's the complete code:

```rust
use std::collections::{HashMap, VecDeque};

pub struct Graph {
    nodes: HashMap<String, Vec<String>>,
}

impl Graph {
    pub fn new() -> Self {
        Graph {
            nodes: HashMap::new(),
        }
    }

    pub fn add_node(&mut self, value: &str) {
        self.nodes.entry(value.to_string()).or_insert(Vec::new());
    }

    pub fn add_edge(&mut self, from: &str, to: &str) {
        if let Some(neighbors) = self.nodes.get_mut(from) {
            neighbors.push(to.to_string());
        }
    }

    pub fn bfs(&self, start: &str) -> Vec<String> {
        let mut visited = HashMap::new();
        let mut queue = VecDeque::new();
        let mut result = Vec::new();

        queue.push_back(start.to_string());
        visited.insert(start.to_string(), true);

        while let Some(node) = queue.pop_front() {
            result.push(node.clone());

            if let Some(neighbors) = self.nodes.get(&node) {
                for neighbor in neighbors {
                    if !visited.contains_key(neighbor) {
                        queue.push_back(neighbor.to_string());
                        visited.insert(neighbor.to_string(), true);
                    }
                }
            }
        }

        result
    }

    pub fn dfs(&self, start: &str) -> Vec<String> {
        let mut visited = HashMap::new();
        let mut result = Vec::new();
        self.dfs_recursive(start, &mut visited, &mut result);
        result
    }

    fn dfs_recursive(&self, node: &str, visited: &mut HashMap<String, bool>, result: &mut Vec<String>) {
        visited.insert(node.to_string(), true);
        result.push(node.to_string());

        if let Some(neighbors) = self.nodes.get(node) {
            for neighbor in neighbors {
                if !visited.contains_key(neighbor) {
                    self.dfs_recursive(neighbor, visited, result);
                }
            }
        }
    }
}

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn test_bfs() {
        let mut graph = Graph::new();
        graph.add_node("A");
        graph.add_node("B");
        graph.add_node("C");
        graph.add_node("D");
        graph.add_edge("A", "B");
        graph.add_edge("A", "C");
        graph.add_edge("B", "D");
        graph.add_edge("C", "D");

        let bfs_result = graph.bfs("A");
        assert_eq!(bfs_result, vec!["A", "B", "C", "D"]);
    }

    #[test]
    fn test_dfs() {
        let mut graph = Graph::new();
        graph.add_node("A");
        graph.add_node("B");
        graph.add_node("C");
        graph.add_node("D");
        graph.add_edge("A", "B");
        graph.add_edge("A", "C");
        graph.add_edge("B", "D");
        graph.add_edge("C", "D");

        let dfs_result = graph.dfs("A");
        assert_eq!(dfs_result, vec!["A", "B", "D", "C"]);
    }
}
```

### Explanation:
- **Graph Structure**: The `Graph` struct uses a `HashMap` to store nodes and their neighbors.
- **Adding Nodes and Edges**: Methods `add_node` and `add_edge` allow you to add nodes and edges to the graph.
- **BFS and DFS**: Methods `bfs` and `dfs` perform breadth-first and depth-first searches, respectively, returning the order of visited nodes.
- **Tests**: The `tests` module contains tests for BFS and DFS to ensure they work correctly.

You can run the tests using `cargo test`. This setup allows you to verify the functionality of your graph implementation without needing a `main` function. If you have any questions or need further adjustments, feel free to ask!

Release 202408210915

clean up, refactor

for example,
was
fs::write(&config_path, config_data).map_err(|e| {
        eprintln!("Unable to write config file: {}", e);
        GameError::ConfigError
    })?;

The Clippy warning you're seeing suggests that you don't need to borrow `config_path` when passing it to `fs::write`. You can pass it directly instead. Here's the corrected code:

```rust
fs::write(config_path, config_data).map_err(|e| {
    eprintln!("Unable to write config file: {}", e);
    GameError::ConfigError
})?;
```

By removing the `&` before `config_path`, you avoid the needless borrow and comply with Clippy's recommendation. This should resolve the warning. Let me know if you need any more help!
