Available on crate feature http only.

Errors that can occur during HTTP proxy protocol operations.

Each variant represents a specific error condition that may arise when implementing or using the HTTP proxy protocol, particularly with the CONNECT method.

Variants (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.

ParseRequestFailed(Error)

Failed to parse the HTTP request due to a specific httparse error.

ParseResponseFailed(Error)

Failed to parse the HTTP response due to a specific httparse error.

HeaderTooLong

HTTP header section exceeds the maximum buffer size.

ConnectionClosedHeaderIncomplete

Connection was closed before the complete HTTP header was received.

MissingMethod

HTTP request is missing the method field.

OnlyConnectSupported

HTTP proxy implementation only supports the CONNECT method.

OnlyBasicAuthSupported

HTTP proxy authentication only supports the Basic scheme.

InvalidBase64Encoding

Provided authorization header contains invalid Base64 encoding.

InvalidCredentials

Provided username/password combination is incorrect.

AuthenticationRequired

Proxy requires authentication but no credentials were provided.

MissingTargetPath

HTTP CONNECT request is missing the target host:port path.

MissingStatusCode

HTTP response is missing the status code.

HttpError(u16, String)

Server returned an HTTP error with specific status code and reason.

Trait Implementations

impl Clone for HttpError

fn clone(&self) -> HttpError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HttpError

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

Formats the value using the given formatter.

impl Display for HttpError

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

Formats the value using the given formatter.

impl Eq for HttpError

impl Error for HttpError

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.

impl From<HttpError> for Error

fn from(e: HttpError) -> Self

Converts to this type from the input type.

impl PartialEq for HttpError

fn eq(&self, other: &HttpError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
