Errors from ureq.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

StatusCode(u16)

When http_status_as_error() is true, 4xx and 5xx response status codes are translated to this error.

This is the default behavior.

§

Http(Error)

Errors arising from the http-crate.

These errors happen for things like invalid characters in header names.

§

BadUri(String)

Error if the URI is missing scheme or host.

§

Protocol(Error)

An HTTP/1.1 protocol error.

This can happen if the remote server ends incorrect HTTP data like missing version or invalid chunked transfer.

§

Io(Error)

Error in io such as the TCP socket.

§

Timeout(Timeout)

Error raised if the request hits any configured timeout.

By default no timeouts are set, which means this error can’t happen.

§

HostNotFound

Error when resolving a hostname fails.

§

RedirectFailed

A redirect failed.

This happens when ureq encounters a redirect when sending a request body such as a POST request, and receives a 307/308 response. ureq refuses to redirect the POST body and instead raises this error.

§

InvalidProxyUrl

Error when creating proxy settings.

§

ConnectionFailed

A connection failed.

This is a fallback error when there is no other explanation as to why a connector chain didn’t produce a connection. The idea is that the connector chain would return some other Error rather than rely om this value.

Typically bespoke connector chains should, as far as possible, map their underlying errors to Error::Io and use the io::ErrorKind to provide a reason.

A bespoke chain is allowed to map to this value, but that provides very little information to the user as to why the connection failed. One way to mitigate that would be to rely on the log crate to provide additional information.

§

BodyExceedsLimit(u64)

A send body (Such as &str) is larger than the content-length header.

§

TooManyRedirects

Too many redirects.

The error can be turned off by setting max_redirects_will_error() to false. When turned off, the last response will be returned instead of causing an error, even if it is a redirect.

The number of redirects is limited to 10 by default.

§

RequireHttpsOnly(String)

The setting https_only is true and the URI is not https.

§

LargeResponseHeader(usize, usize)

The response header, from status up until body, is too big.

§

ConnectProxyFailed(String)

Attempt to connect to a CONNECT proxy failed.

§

TlsRequired

The protocol requires TLS (https), but the connector did not create a TLS secured transport.

This typically indicates a fault in bespoke Connector chains.

§

Other(Box<dyn Error + Sync + Send>)

Some other error occured.

This is an escape hatch for bespoke connector chains having errors that don’t naturally map to any other error. For connector chains we recommend:

  1. Map to Error::Io as far as possible.
  2. Map to other Error where reasonable.
  3. Fall back on Error::Other.
  4. As a last resort Error::ConnectionFailed.

ureq does not produce this error using the default connectors.

Implementations§

§

impl Error

pub fn into_io(self) -> Error

Convert the error into a std::io::Error.

If the error is Error::Io, we unpack the error. In othe cases we make an std::io::ErrorKind::Other.
