askama_web

A compatibility add-on for askama to support many different web frameworks.

Example

E.g. if you are using axum, then add askama_web with the feature "axum-0.8" to your Cargo.toml:

[dependencies]
askama_web = { version = "0.12.0", features = ["axum-0.8"] }

Then just add #[derive(WebTemplate)] to your Askama templated struct or enum:

use askama::Template;
use askama_web::WebTemplate;
use axum::Router;
use axum::routing::get;

#[derive(Template, WebTemplate)]
#[template(path = "hello.html")]
struct HelloTemplate {
    name: String,
}

async fn hello() -> HelloTemplate {
    HelloTemplate {
        name: "world".to_string(),
    }
}

let app = Router::new().route("/", get(hello));

By selecting the feature "axum-0.8", HelloTemplate will implement axum::response::IntoResponse. The user will receive a "Status: 200", "Content-Type: text/html; charset=utf-8" response with the rendered struct as body.

Feature flags / web framework selection

These web frameworks are currently implemented and can be selected with their respective feature flag:

• "actix-web-4": implements Responder for actix-web in version 4
• "axum-0.8" / "axum-core-0.5": implements IntoResponse for axum in version 0.8 / axum-core in version 0.5
• "poem-3": implements IntoResponse for poem in version 3.x
• "rocket-0.5": implements Responder for rocket in version 0.5
• "salvo-0.77" / "salvo_core-0.77": implements Scribe for salvo in version 0.77 / salvo_core in version 0.77
• "trillium-0.2": implements Handler for trillium in version 0.2
• "viz-0.10" / "viz-core-0.10": implements IntoResponse for viz in version 0.10 / viz-core in version 0.10
• "warp-0.3": implements Reply for warp in version 0.3

As well as these logging / debugging facilities to print error messages if a template could not be rendered:

• "eprintln": using rust's built-in eprintln!() macro
• "log-0.4": using log as logging framework
• "tracing-0.1": using tracing as logging framework

Some older versions are implemented, too:

• "axum-0.7" / "axum-core-0.4": implements IntoResponse for axum in version 0.7 / axum-core in version 0.4
• "salvo-0.76" / "salvo_core-0.76": implements Scribe for salvo in version 0.76 / salvo_core in version 0.76
