Function fs_create_dir 

pub fn fs_create_dir(path: &Path) -> Result<(), FpgadError>

Recursively create directories up to the specified path.

This is a convenient wrapper around std::fs::create_dir_all that provides trace logging and automatic error conversion to FpgadError::IOCreate. It will create all missing parent directories in the path.

Arguments

• path - The directory path to create (including all parents)

Returns: Result<(), FpgadError>

• Ok(()) - Directory created (or already existed)
• Err(FpgadError::IOCreate) - If directory creation fails (permissions, etc.)

Examples

// Create nested directories
fs_create_dir(Path::new("/sys/kernel/config/device-tree/overlays/my_overlay"))?;
