Struct Path

pub struct Path<T>(pub T);

Extract path parameters from the request URL

Example

use torch_web::extractors::Path;

// Extract a single parameter
async fn get_user(Path(user_id): Path<u32>) {
    // user_id is automatically parsed from the URL
}

// Extract multiple parameters as a tuple
async fn get_post(Path((user_id, post_id)): Path<(u32, u32)>) {
    // Extracts from "/users/:user_id/posts/:post_id"
}

// Extract into a custom struct
#[derive(serde::Deserialize)]
struct PostPath {
    user_id: u32,
    post_id: u32,
}

async fn get_post_struct(Path(path): Path<PostPath>) {
    // Automatically deserializes path parameters
}
