Struct Query 

pub struct Query<T>(pub T);

Extractor for query parameters.

Extracts typed parameters from the query string. The type must implement serde::Deserialize and be stored in extensions during connection establishment.

Examples

Search Parameters

use wsforge::prelude::*;
use serde::Deserialize;

#[derive(Deserialize)]
struct SearchQuery {
    q: String,
    limit: Option<u32>,
}

async fn search(Query(params): Query<SearchQuery>) -> Result<String> {
    let limit = params.limit.unwrap_or(10);
    Ok(format!("Searching for '{}' (limit: {})", params.q, limit))
}

Tuple Fields

0: T
