pub struct Json<T>(pub T);Expand description
Wrapper used to create Json Http Responses,
as well as to extract Json from Http Request bodies.
§Examples
§Creating a Json Response
use serde_json::json;
use rama_http_types::{IntoResponse, response::Json};
async fn handler() -> impl IntoResponse {
Json(json!({
"name": "john",
"age": 30,
"is_student": false
}))
}§Extracting Json from a Request
use serde_json::json;
use rama_http_types::response::Json;
#[derive(Debug, serde::Deserialize)]
struct Input {
name: String,
age: u8,
alive: Option<bool>,
}
async fn handler(Json(input): Json<Input>) {
if !input.alive.unwrap_or_default() {
bury(&input.name);
}

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