Function compile_to_dir 

pub fn compile_to_dir(
    source: &str,
    output_dir: &Path,
) -> Result<(), CompileError>

Compile LOGOS source and write output to a directory as a Cargo project.

Creates a complete Cargo project structure with:

• src/main.rs containing the generated Rust code
• Cargo.toml with runtime dependencies
• crates/ directory with runtime crate copies

Arguments

• source - LOGOS source code as a string
• output_dir - Directory to create the Cargo project in

Errors

Returns CompileError if:

• Compilation fails (wrapped as CompileError::Parse)
• File system operations fail (wrapped as CompileError::Io)

Example

let source = "## Main\nShow \"Hello\".";
compile_to_dir(source, Path::new("/tmp/my_project"))?;
// Now /tmp/my_project is a buildable Cargo project
