Struct actix_web::web::Path[][src]

pub struct Path<T>(_);
Expand description

Extract typed data from request path segments.

Use PathConfig to configure extraction option.

Examples

use actix_web::{get, web};

// extract path info from "/{name}/{count}/index.html" into tuple
// {name}  - deserialize a String
// {count} - deserialize a u32
#[get("/{name}/{count}/index.html")]
async fn index(path: web::Path<(String, u32)>) -> String {
    let (name, count) = path.into_inner();
    format!("Welcome {}! {}", name, count)
}

Path segments also can be deserialized into any type that implements serde::Deserialize. Path segment labels will be matched with struct field names.

use actix_web::{get, web};
use serde::Deserialize;

#[derive(Deserialize)]
struct Info {
    name: String,
}

// extract `Info` from a path using serde
#[get("/{name}")]
async fn index(info: web::Path<Info>) -> String {
    format!("Welcome {}!", info.name)
}
