Struct ValidatedQuery 

pub struct ValidatedQuery<T>(pub T);

Query parameters extractor with automatic validation

This extractor deserializes query parameters and automatically validates them.

Example

use lmrc_http_common::extractors::ValidatedQuery;
use serde::Deserialize;
use validator::Validate;

#[derive(Deserialize, Validate)]
struct Pagination {
    #[validate(range(min = 1, max = 100))]
    page: u32,
    #[validate(range(min = 1, max = 100))]
    per_page: u32,
}

async fn list_items(
    ValidatedQuery(params): ValidatedQuery<Pagination>
) -> &'static str {
    "Items list"
}

Trait Implementations

impl<T: Clone> Clone for ValidatedQuery<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ValidatedQuery<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for ValidatedQuery<T>

fn default() -> ValidatedQuery<T>

Returns the “default value” for a type.

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

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

type Rejection = HttpError

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

fn from_request<'life0, 'async_trait>( req: Request, state: &'life0 S, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Perform the extraction.
