Struct Query

pub struct Query<T>(pub T);

Extract query parameters from the request URL

Example

use torch_web::extractors::Query;
use std::collections::HashMap;
use serde::Deserialize;

// Extract as HashMap
async fn search(Query(params): Query<HashMap<String, String>>) {
    // params contains all query parameters
}

// Extract into a custom struct
#[derive(Deserialize)]
struct SearchParams {
    q: String,
    page: Option<u32>,
    limit: Option<u32>,
}

async fn search_typed(Query(params): Query<SearchParams>) {
    // Automatically deserializes and validates query parameters
}
