Struct QueryString

pub struct QueryString<T>(pub T);

Actix-web’s web::Query modified to work with serde-querystring

QueryStringConfig allows to configure extraction process.

Example

use actix_web::{web, App};
use serde::Deserialize;
use serde_querystring_actix::QueryString;

#[derive(Debug, Deserialize)]
pub enum ResponseType {
   Token,
   Code
}

#[derive(Deserialize)]
pub struct AuthRequest {
   id: u64,
   response_type: ResponseType,
}

// Use `QueryString` extractor for query information (and destructure it within the signature).
// This handler gets called only if the request's query string contains a `username` field.
// The correct request for this handler would be `/index.html?id=64&response_type=Code"`.
// For more example visit the serde-querystring crate itself.
async fn index(QueryString(info): QueryString<AuthRequest>) -> String {
    format!("Authorization request for client with id={} and type={:?}!", info.id, info.response_type)
}

fn main() {
    let app = App::new().service(
       web::resource("/index.html").route(web::get().to(index))); // <- use `Query` extractor
}

where T: DeserializeOwned,

Get query parameters from the path

Trait Implementations

impl<T: Clone> Clone for QueryString<T>

fn clone(&self) -> QueryString<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for QueryString<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Deref for QueryString<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> DerefMut for QueryString<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T: Display> Display for QueryString<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> FromRequest for QueryString<T>

where T: DeserializeOwned,

type Error = Error

The associated error which can be returned.

type Future = Ready<Result<QueryString<T>, Error>>

Future that resolves to a Self.

fn from_request(req: &HttpRequest, _: &mut Payload) -> Self::Future

Create a Self from request parts asynchronously.

fn extract(req: &HttpRequest) -> Self::Future

Create a Self from request head asynchronously.

impl<T: Ord> Ord for QueryString<T>

fn cmp(&self, other: &QueryString<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for QueryString<T>

fn eq(&self, other: &QueryString<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: PartialOrd> PartialOrd for QueryString<T>

fn partial_cmp(&self, other: &QueryString<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
