dir-structure

A library to make it easier to represent directory structures as plain Rust structures, and reducing the boiler-plate associated with creating and manipulating them.

A quick example:

#[derive(dir_structure::DirStructure)]
struct Dir {
    #[dir_structure(path = "input.txt")]
    input: String,
    #[dir_structure(path = "output.txt")]
    output: String,
}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    use dir_structure::DirStructureItem;
    let path = std::path::Path::new("my_dir");
    // to read a `Dir` instance
    let dir = Dir::read(path)?;
    // to write a `Dir` instance
    dir.write(path)?;
    
    // or simply with a struct literal
    Dir {
        input: "Hello, world!".to_string(),
        output: "Hello, world!".to_string(),
    }.write(path)?;
    
    Ok(())
}
