Struct ntex::web::types::Path [−][src]
pub struct Path<T> { /* fields omitted */ }
Expand description
Extract typed information from the request’s path.
PathConfig allows to configure extraction process.
Example
use ntex::web;
/// extract path info from "/{username}/{count}/index.html" url
/// {username} - deserializes to a String
/// {count} - - deserializes to a u32
async fn index(info: web::types::Path<(String, u32)>) -> String {
format!("Welcome {}! {}", info.0, info.1)
}
fn main() {
let app = web::App::new().service(
web::resource("/{username}/{count}/index.html") // <- define path parameters
.route(web::get().to(index)) // <- register handler with `Path` extractor
);
}
It is possible to extract path information to a specific type that
implements Deserialize
trait from serde.
use ntex::web;
#[derive(serde::Deserialize)]
struct Info {
username: String,
}
/// extract `Info` from a path using serde
async fn index(info: web::types::Path<Info>) -> Result<String, web::Error> {
Ok(format!("Welcome {}!", info.username))
}
fn main() {
let app = web::App::new().service(
web::resource("/{username}/index.html") // <- define path parameters
.route(web::get().to(index)) // <- use handler with Path` extractor
);
}
