Struct Query

pub struct Query<T>(pub T);

Extractor that deserializes query strings into some type.

T is expected to implement serde::Deserialize.

Tuple Fields

0: T

Implementations

impl<T> Query<T>

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

pub fn parse_query_str( query: &str, ) -> Result<Query<T>, FailedToDeserializeQueryString>

Create a Query<T> directly from the query str, can be useful to combine this method as part of another extractor or otherwise impossible combination.

Trait Implementations

impl<T> Clone for Query<T>

where T: Clone,

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Query<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> FromRequestContextRefPair for Query<T>

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

type Rejection = FailedToDeserializeQueryString

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_context_ref_pair( _ctx: &Context, parts: &Parts, ) -> Result<Query<T>, <Query<T> as FromRequestContextRefPair>::Rejection>

Perform the extraction.

impl<T> OptionalFromRequestContextRefPair for Query<T>

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

type Rejection = FailedToDeserializeQueryString

If the extractor fails, it will use this “rejection” type.

async fn from_request_context_ref_pair( _ctx: &Context, parts: &Parts, ) -> Result<Option<Query<T>>, <Query<T> as OptionalFromRequestContextRefPair>::Rejection>

Perform the extraction.
