Struct LayoutEngine 

pub struct LayoutEngine { /* private fields */ }

Renders HTML layout templates using MiniJinja.

The engine always includes a built-in "default" layout. Additional layouts are loaded from {templates_path}/layouts/*.html at construction time and override the built-in if they share the same name.

Auto-escaping is disabled because the content variable is already rendered HTML.

Implementations

impl LayoutEngine

pub fn try_new(templates_path: &str) -> Result<Self, Error>

Create a LayoutEngine that loads custom .html layouts from {templates_path}/layouts/ in addition to the built-in "default" layout.

Returns an error if any layout file contains invalid template syntax.

pub fn new(templates_path: &str) -> Self

Create a LayoutEngine that loads custom .html layouts from {templates_path}/layouts/ in addition to the built-in "default" layout.

Panics

Panics if any layout file contains invalid template syntax. Use try_new for a fallible alternative.

pub fn builtin_only() -> Self

Create a LayoutEngine with only the built-in "default" layout.

Useful in tests or when no custom layouts are needed.

pub fn render( &self, layout_name: &str, context: &Value, ) -> Result<String, Error>

Render the named layout with the provided MiniJinja context.

layout_name is looked up as layouts/{layout_name}.html. Returns an error if the layout does not exist or if rendering fails.
