Struct Engines

pub struct Engines {
    pub tera: Tera,
    pub handlebars: Handlebars<'static>,
    pub minijinja: Environment<'static>,
}

A structure exposing access to templating engines.

Calling methods on the exposed template engine types may require importing types from the respective templating engine library. These types should be imported from the reexported crate at the root of rocket_dyn_templates to avoid version mismatches. For instance, when registering a Tera filter, the tera::Value and tera::Result types are required. Import them from rocket_dyn_templates::tera. The example below illustrates this:

use std::collections::HashMap;

use rocket_dyn_templates::{Template, Engines};
use rocket_dyn_templates::tera::{self, Value};

fn my_filter(value: &Value, _: &HashMap<String, Value>) -> tera::Result<Value> {
    ...
}

fn main() {
    rocket::build()
        // ...
        .attach(Template::custom(|engines: &mut Engines| {
            engines.tera.register_filter("my_filter", my_filter);
        }))
        // ...
}

Fields

tera: Tera

A Tera templating engine.

This field is only available when the tera feature is enabled. When calling methods on the Tera instance, ensure you use types imported from rocket_dyn_templates::tera to avoid version mismatches.

handlebars: Handlebars<'static>

The Handlebars templating engine.

This field is only available when the handlebars feature is enabled. When calling methods on the Handlebars instance, ensure you use types imported from rocket_dyn_templates::handlebars to avoid version mismatches.

minijinja: Environment<'static>

The minijinja templating engine.

This field is only available when the minijinja feature is enabled. When calling methods on the Environment instance, ensure you use types imported from rocket_dyn_templates::minijinja to avoid version mismatches.
