Struct TemplateEngine 

pub struct TemplateEngine { /* private fields */ }

Wraps MiniJinja and provides site-generation-specific rendering.

Implementations

impl TemplateEngine

pub fn init(config: TemplateConfig) -> Result<Option<Self>>

Initializes the template engine from a template directory.

Uses a path-based loader for lazy template resolution. Returns Ok(None) if the template directory does not exist (graceful fallback for projects without templates).

pub fn render_page( &self, template_name: &str, page_content: &str, frontmatter: &HashMap<String, Value>, site_globals: &HashMap<String, Value>, ) -> Result<String>

Renders a page through the template chain.

Arguments

• template_name — template to render (e.g. "page.html")
• page_content — compiled HTML content from staticdatagen
• frontmatter — parsed frontmatter as JSON key-value pairs
• site_globals — site-level variables (name, base_url, etc.)

pub fn site_globals_from_config(config: &SsgConfig) -> HashMap<String, Value>

Builds site-level globals from an SsgConfig.

pub fn load_data_files(content_dir: &Path) -> HashMap<String, Value>

Loads data files from a data/ directory into the context.

Supports .toml, .json, and .yml/.yaml files. Files are accessible as {{ data.filename }} in templates.

Example: data/nav.toml → {{ data.nav.links }}
