Struct Error 

pub struct Error { /* private fields */ }

An error building a request, sending it, or reading the response body.

Implementations

impl Error

pub fn is_builder(&self) -> bool

The request could not be built: an invalid URL, header, or body.

pub fn is_request(&self) -> bool

The service failed to send the request or to receive a response: connection refused, a timeout layer gave up, and so on. Error::source is the service’s error.

pub fn is_body(&self) -> bool

Reading the response body failed.

pub fn is_decode(&self) -> bool

The response body could not be decoded.

pub fn is_io(&self) -> bool

A file could not be read or written: an Upload whose file is missing, or Response::save_to failing to write. Error::source is the std::io::Error.

pub fn is_timeout(&self) -> bool

Whether the request timed out: a reqwest timeout, tower’s timeout layer, or an idle_timeout of server-sent events.

pub fn is_connect(&self) -> bool

Whether connecting to the server failed (only known for reqwest, and not on WebAssembly, where fetch does not tell).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn StdError + '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.
