Trait FileSystem 

pub trait FileSystem: Send + Sync {
    // Required methods
    fn read_to_string(&self, path: &Path) -> Result<String>;
    fn write(&self, path: &Path, contents: &str) -> Result<()>;
    fn glob(&self, base: &Path, pattern: &str) -> Result<Vec<PathBuf>>;
    fn exists(&self, path: &Path) -> bool;
    fn create_dir_all(&self, path: &Path) -> Result<()>;
}

Abstraction over filesystem operations for testability.

Required Methods

fn read_to_string(&self, path: &Path) -> Result<String>

Reads the contents of a file as a UTF-8 string.

fn write(&self, path: &Path, contents: &str) -> Result<()>

Writes string contents to a file, creating parent directories as needed.

fn glob(&self, base: &Path, pattern: &str) -> Result<Vec<PathBuf>>

Lists all files matching a glob pattern in a directory.

fn exists(&self, path: &Path) -> bool

Checks if a path exists.

fn create_dir_all(&self, path: &Path) -> Result<()>

Creates a directory and all parent directories.
