Struct LxJson 

Source 
pub struct LxJson<T>(pub T);
Expand description

A version of axum::Json which conforms to Lexe’s (JSON) API. It can be used as either an extractor or a response.

axum::Json is banned because:

  • Rejections return JsonRejection which is just a string HTTP body.
  • Response serialization failures likewise return just a string body.

NOTE: This must only be used for forming success API responses, i.e. T in Result<T, E>, because its IntoResponse impl uses StatusCode::OK. Our API error types, while also serialized as JSON, have separate IntoResponse impls which return error statuses.

Source§

impl<T: DeserializeOwned, S: Send + Sync> FromRequest<S> for LxJson<T>

Source§

type Rejection = LxRejection

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

async fn from_request( req: Request<Body>, state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.

impl<T: Serialize> IntoResponse for LxJson<T>

Source§

fn into_response(self) -> Response<Body>

Create a response.
Source§

impl<T: PartialEq> PartialEq for LxJson<T>

Source§

fn eq(&self, other: &Self) -> 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.
