Struct serde_qs::actix::QsForm

pub struct QsForm<T>(/* private fields */);

Extract typed information from from the request’s form data.

Example

use actix_web::{web, App, HttpResponse};
use serde_qs::actix::QsForm;

#[derive(Debug, Deserialize)]
pub struct UsersFilter {
   id: Vec<u64>,
}

// Use `QsForm` extractor for Form information.
// Content-Type: application/x-www-form-urlencoded
// The correct request payload for this handler would be `id[]=1124&id[]=88`
async fn filter_users(info: QsForm<UsersFilter>) -> HttpResponse {
    HttpResponse::Ok().body(
        info.id.iter().map(|i| i.to_string()).collect::<Vec<String>>().join(", ")
    )
}

fn main() {
    let app = App::new().service(
       web::resource("/users")
           .route(web::get().to(filter_users)));
}

Trait Implementations

impl<T: Debug> Debug for QsForm<T>

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

Formats the value using the given formatter.

impl<T> Deref for QsForm<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> DerefMut for QsForm<T>

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

Mutably dereferences the value.

impl<T> FromRequest for QsForm<T>

where T: DeserializeOwned + Debug,

type Error = Error

The associated error which can be returned.

type Future = Pin<Box<dyn Future<Output = Result<QsForm<T>, Error>>>>

Future that resolves to a Self.

fn from_request(req: &HttpRequest, payload: &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 QsForm<T>

fn cmp(&self, other: &QsForm<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 + PartialOrd,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for QsForm<T>

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T: PartialOrd> PartialOrd for QsForm<T>

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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