Enum HttpError 

pub enum HttpError {
    ConnectionClosed,
    H2(H2Error),
    Io(Error),
    InvalidUrl(String),
    Parse,
    InvalidMessage(String),
    MaxSizeExceeded(String),
    Timeout,
    FlowControl,

}

Errors produced by the HTTP client.

Variants

ConnectionClosed

The connection was closed unexpectedly.

H2(H2Error)

HTTP/2 framing error.

Io(Error)

I/O error.

InvalidUrl(String)

Invalid URL or path.

Parse

Response parsing error.

InvalidMessage(String)

Parsed message is syntactically valid but rejected on semantic grounds — e.g., conflicting Transfer-Encoding + Content-Length (RFC 9112 §6.3 request smuggling defense), multiple Content-Length headers with different values, header values containing CR/LF/NUL, or unsupported transfer codings.

MaxSizeExceeded(String)

A configured resource cap (max header section, max body, max chunk, max trailer, max decompressed size) was exceeded.

Timeout

Request timed out.

FlowControl

H2 flow control blocked and could not be resolved.

AllConnectionsFailed

All connections in a pool failed.

Protocol(String)

Protocol error (unexpected event, bad state).

Decompress(String)

Decompression error.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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<Error> for HttpError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<H2Error> for HttpError

fn from(source: H2Error) -> Self

Converts to this type from the input type.
