Dynamic path parameters

[melokki]

Hello actix community
I am new in this ecosystem so please excuse my stupid questions :)

I've started to write a very small application using actix and I have the following issue that I don't understand
How can I write an endpoint that can accept dynamic url parameters?
For example, I am writing an endpoint to pass some information about an image and I want something like this:
/images/w200/h200/filename
All good so far, the issue is when I am missing some params, for example, if I call the endpoint like this:
/images/w200/filename, it won't work

How can I have wildcard/dynamic path parameters (don't know how exactly to call it) so I can call the endpoint with a variable number of parameters?

Hope I explained it good enough

my code so far looks like this

use actix_web::{get, web, HttpResponse, Responder};

use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize, Debug)]
struct Image {
    width: Option<String>,
    height: Option<String>,
    filename: Option<String>,
}

// I want to get rid of the width, height, filename segments and have something like * to catch all the params
#[get("/images/{width}/{height}/{filename}")]
async fn show(params: web::Path<Image>) -> impl Responder {
    println!("{:?}", params);
    HttpResponse::Ok().json("foo")
}

Ok, I managed to find the solution in the documentation. I didn't saw it while reading the docs :D

// this will catch all the url parameters
#[get("/images/{tail:.*}")]
async fn show(params: web::Path<String>) -> impl Responder {
    println!("{:?}", params);
    HttpResponse::Ok().json("foo")
}
