Struct fastly::http::request::SendError

pub struct SendError { /* private fields */ }

An error that occurred while sending a request.

While the body of a request is always consumed when sent, you can recover the headers and other request metadata of the request that failed using SendError::into_sent_req().

use SendError::root_cause() to inspect details about what caused the error.

Implementations

impl SendError

pub fn backend_name(&self) -> &str

Get the name of the backend that returned this error.

pub fn root_cause(&self) -> &SendErrorCause

Get the underlying cause of this SendError.

This is the same cause that would be returned by err.source().downcast_ref::<SendErrorCause>(), but more direct.

pub fn into_sent_req(self) -> Request

Convert the error back into the request that was originally sent.

Since the original request’s body is consumed by sending it, the body in the returned request is empty. To add a new body to the request, use Request::with_body(), for example:

if let Err(e) = bereq.send("my_backend") {
    let new_body = Body::from("something new");
    let new_req = e.into_sent_req().with_body(new_body);
    new_req.send("my_other_backend")?;
}

impl Error for SendError

fn source(&self) -> Option<&(dyn Error + 'static)>

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()
