Struct FilesystemProvider 

pub struct FilesystemProvider { /* private fields */ }

Loads email templates from the filesystem with locale-based fallback.

Templates are stored as .md files with YAML frontmatter. Localized variants live in subdirectories named after the locale (e.g. de/welcome.md). When a localized file is not found, the provider falls back to the root template (welcome.md).

Path traversal attempts (names or locales containing .., /, or \) are rejected and return an error.

Implementations

impl FilesystemProvider

pub fn new(base_dir: impl Into<PathBuf>) -> Self

Create a provider rooted at base_dir.

The directory does not need to exist at construction time; errors are returned when a template is requested and the file cannot be found.

Trait Implementations

impl TemplateProvider for FilesystemProvider

fn get(&self, name: &str, locale: &str) -> Result<EmailTemplate, Error>

Return the template identified by name, resolving to the given locale when available. Pass an empty string for locale to request the default.
