Struct TemplateEngine 

pub struct TemplateEngine { /* private fields */ }

Template engine that manages Handlebars templates

Implementations

impl TemplateEngine

pub fn from_embedded() -> Result<Self>

Create a template engine from embedded templates

pub fn empty() -> Self

Create an empty template engine (fallback mode)

pub fn reload(&self) -> Result<()>

Reload templates (no-op for embedded templates, kept for API compatibility)

pub fn render<T>(&self, template_name: &str, data: &T) -> Result<String>

where T: Serialize,

Render a template with the given data

The lock is taken with unwrap_or_else(|e| e.into_inner()) rather than unwrap(). This is shared infrastructure: a single panic while any reader held it would poison the RwLock and make every subsequent prompt build in the process panic, turning one transient fault into a permanent outage. The Handlebars registry behind it is immutable after construction, so recovering the guard is safe.

pub fn render_json(&self, template_name: &str, data: &Value) -> Result<String>

Render a template with raw JSON data

pub fn has_template(&self, template_name: &str) -> bool

Check if a template exists

pub fn get_templates(&self) -> Vec<String>

Get all registered template names
