Struct Query 

pub struct Query<T>(pub T)
where
    T: for<'de> Deserialize<'de> + Send;

Represented as url query data

when request with url query, we can using this struct to inject data, note: the struct must impl serde::Deserialize and Send

Example

#[derive(Deserialize, Debug)]
struct Params {
    name: String,
    zip: String,
}

pub async fn handle(Query(params) : Query<Params>) -> String {
    format!("received params: {:?}", params)
}

Tuple Fields

0: T

Trait Implementations

impl<T> FromRequest for Query<T>

where T: for<'de> Deserialize<'de> + Send,

Implements query string extraction for any type that implements Deserialize

This implementation allows automatic deserialization of query string parameters into a strongly-typed struct using serde_qs.

type Output<'r> = T

type Error = ParseError

async fn from_request<'r>( req: &'r RequestContext<'_, '_>, _body: OptionReqBody, ) -> Result<Self::Output<'r>, Self::Error>
