Abstract file system interface for file loading.

This trait allows the loader to work with different file system backends:

• DiskFileSystem: Reads from the actual filesystem (default)
• VirtualFileSystem: Reads from an in-memory file map (for WASM)

Required Methods

fn read(&self, path: &Path) -> Result<Arc<str>, LoadError>

Read file content at the given path.

Errors

Returns LoadError::Io if the file cannot be read.

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

Check if a file exists at the given path.

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

Check if a path is a GPG-encrypted file.

For virtual filesystems, this always returns false since encrypted files should be decrypted before being added.

fn normalize(&self, path: &Path) -> PathBuf

Normalize a path for this filesystem.

For disk filesystems, this makes paths absolute. For virtual filesystems, this just cleans up the path.

Provided Methods

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

Expand a glob pattern and return matching paths.

Errors

Returns an error string if the pattern is invalid.
