Web Route

web-route provides an ergonomic way to define and manage web server routes in Rust.

Most web frameworks define routes using &str templates (e.g. "/foo/{param}"). This approach can become error-prone when you need to:

• Generate a callable version of a route (with parameters populated), for use in internal redirects, integration tests, etc.
• Join routes across nested routers — without having to worry about whether strings have leading/trailing slashes or resorting to format!() gymnastics.

Features

• Cleanly define and join route segments
• Generate template routes for framework registration
• Generate populated routes with runtime parameters
• Slash handling is automatic and consistent

Usage

For complete examples, see the examples and integration tests.

use web_route::WebRoute;

// Define routes for parent and child routers
let parent_route = WebRoute::new("/parent/{param}");
let child_route = WebRoute::new("/child/route");

// Join routes — no need to worry about trailing slashes
let full_route = parent_route.join(&child_route);

// Convert to a route template (for use with frameworks like `axum`)
let template = parent_route.as_template_route();
assert_eq!(template, "/parent/{param}");

// Generate a fully-populated route with parameter values
let populated = full_route
    .as_populated_route(&RouteParams {
        param: "foobar".to_string(),
    })
    .unwrap();
assert_eq!(populated, "/parent/foobar/child/route");

#[derive(serde::Serialize)]
struct RouteParams {
    param: String,
}

Potential Improvements

• Enable compile-time validation of routes and parameters for even greater safety.
