Implementations

impl EngineBuilder

pub fn config(self, config: TemplateConfig) -> Self

Sets the template configuration.

If not called, TemplateConfig::default() is used.

pub fn function<N, F, Rv, Args>(self, name: N, f: F) -> Self

where N: Into<Cow<'static, str>> + Send + 'static, F: Function<Rv, Args> + Send + Sync + 'static, Rv: FunctionResult, Args: for<'a> FunctionArgs<'a>,

Registers a custom MiniJinja global function.

name is the name used in templates (e.g. "greet"), f is any value that implements minijinja::functions::Function.

pub fn filter<N, F, Rv, Args>(self, name: N, f: F) -> Self

where N: Into<Cow<'static, str>> + Send + 'static, F: Function<Rv, Args> + Send + Sync + 'static, Rv: FunctionResult, Args: for<'a> FunctionArgs<'a>,

Registers a custom MiniJinja filter.

name is the filter name used in templates (e.g. "shout"), f is any value that implements minijinja::functions::Function.

pub fn locale_resolvers(self, resolvers: Vec<Arc<dyn LocaleResolver>>) -> Self

Overrides the locale resolver chain.

The resolvers are tried in order; the first one that returns Some wins. When not called, a default chain of QueryParamResolver, CookieResolver, AcceptLanguageResolver, and (when the session feature is enabled) SessionResolver is used.

pub fn build(self) -> Result<Engine>

Builds and returns the Engine.

Errors

Returns Error if the locales directory is unreadable or a locale YAML file cannot be parsed.
