Struct ValidatedForm 

pub struct ValidatedForm<T>(pub T);

Validated form extractor

Automatically deserializes and validates form data using the validator crate. Returns 422 Unprocessable Entity with validation errors if validation fails.

Type Parameters

• T: The form type, must implement Deserialize and Validate

Example

use acton_htmx::extractors::ValidatedForm;
use axum::response::Html;
use serde::Deserialize;
use validator::Validate;

#[derive(Debug, Deserialize, Validate)]
struct SignupForm {
    #[validate(email)]
    email: String,
    #[validate(length(min = 8, max = 100))]
    password: String,
    #[validate(must_match(other = "password"))]
    password_confirmation: String,
}

async fn signup(ValidatedForm(form): ValidatedForm<SignupForm>) -> Html<String> {
    // form is guaranteed to be valid here
    Html(format!("Signed up as {}", form.email))
}

impl<T: Clone> Clone for ValidatedForm<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ValidatedForm<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for ValidatedForm<T>

fn default() -> ValidatedForm<T>

Returns the “default value” for a type.

impl<T, S> FromRequest<S> for ValidatedForm<T>

where T: DeserializeOwned + Validate + 'static, S: Send + Sync + 'static,

type Rejection = ValidationError

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(req: Request, state: &S) -> Result<Self, Self::Rejection>
