Struct Query 

pub struct Query<T>(pub T);

Axum extractor that deserializes URL query parameters into T and then sanitizes it.

Returns a 400 Bad Request error if the query string cannot be deserialized into T. T must implement both serde::de::DeserializeOwned and crate::sanitize::Sanitize.

Example

use modo::extractor::Query;
use modo::sanitize::Sanitize;
use serde::Deserialize;

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

impl Sanitize for SearchParams {
    fn sanitize(&mut self) { self.q = self.q.trim().to_lowercase(); }
}

async fn search(Query(params): Query<SearchParams>) {
    // params.q is already trimmed and lowercased
}

Trait Implementations

impl<S, T> FromRequestParts<S> for Query<T>

where S: Send + Sync, T: DeserializeOwned + Sanitize,

type Rejection = Error

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( parts: &mut Parts, state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.
