Struct TemplateRegistry 

pub struct TemplateRegistry<'a> { /* private fields */ }

Every Handlebars template the server can render.

Implementations

impl<'a> TemplateRegistry<'a>

pub fn empty() -> Self

A registry holding only the embedded base layout, plus the built-in helpers and strict mode. Touches no files.

Panics

Never in practice: the only template registered is compiled into the binary, so a failure here means this crate shipped a layout that does not parse, which its own tests would have caught.

pub fn from_dir(root: impl AsRef<Path>) -> Result<Self, TemplateError>

Loads every template under root’s layouts, pages and partials, on top of the embedded base layout.

Errors

TemplateError::ReadDirectory if root or a subdirectory is unreadable, TemplateError::ReservedName if a file would shadow the embedded layout, TemplateError::NoPages if no page templates exist, or TemplateError::Compile if a template does not compile.

pub fn register_helper( &mut self, name: &str, helper: Box<dyn HelperDef + Send + Sync + 'a>, )

Registers an extra helper, for a project that needs one.

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

Whether a template with this name is registered.

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

where T: Serialize,

Renders name against data.

Errors

TemplateError::Render, most often because strict mode caught a field the template asked for and the data did not supply.
