Enum Error 

pub enum Error {
    Dns,
    NoAddress,
    Connect,
    Tls(Error),
    Io,
    BadResponse,
    Timeout,
}

Why a request failed.

Variants

Dns

The host name would not resolve — usually a lease with no usable resolver, worth telling apart from a server that is down.

NoAddress

The name resolved to no addresses.

Connect

The TCP connection could not be made.

Tls(Error)

The TLS layer failed — including, deliberately, certificate rejection, and a clock nothing has set yet.

Io

Writing the request or reading the response failed.

BadResponse

What came back was not an HTTP response this could take apart.

Timeout

The exchange took longer than Client::timeout.

Trait Implementations

impl Debug for Error

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

impl Display for Error

One line, for the console.

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

impl Error for Error

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
