[][src]Struct rocket_contrib::templates::Engines

pub struct Engines {
    pub tera: Tera,
}

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_contrib to avoid version mismatches. For instance, when registering a Tera filter, the tera::Value and tera::Result types are required. Import them from rocket_contrib::templates::tera. The example below illustrates this:

use std::collections::HashMap;

use rocket_contrib::templates::{Template, Engines};
use rocket_contrib::templates::tera::{self, Value};

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

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_templates feature is enabled. When calling methods on the Tera instance, ensure you use types imported from rocket_contrib::templates::tera to avoid version mismatches.
