Struct Form 

pub struct Form<T>(pub T)
where
    T: for<'de> Deserialize<'de> + Send;

Represented as form data

when post as a application/x-www-form-urlencoded, we can using this struct to inject data, note: the struct must impl serde::Deserialize and Send

Example

#[derive(Deserialize, Debug)]
struct Params {
    name: String,
    zip: String,
}

pub async fn handle(Form(params) : Form<Params>) -> String {
    format!("received params: {:?}", params)
}

Trait Implementations

impl<T> FromRequest for Form<T>

where T: for<'de> Deserialize<'de> + Send,

Extracts form data from request body

This implementation expects the request body to be URL-encoded form data and deserializes it into the target type using serde_urlencoded.

type Output<'r> = Form<T>

type Error = ParseError

async fn from_request<'r>( req: &'r RequestContext<'_, '_>, body: OptionReqBody, ) -> Result<Self::Output<'r>, Self::Error>
