Struct Error

pub struct Error { /* private fields */ }

Represents errors that can occur handling HTTP streams.

Formatting

The Display implementation of this type will only print the details of this level of error, even though it may have been caused by another error and contain that error in its source. To print all the relevant information, including the source chain, using something like std::error::Report, or equivalent 3rd party types.

The contents of the formatted error message of this specific Error type is unspecified. You must not depend on it. The wording and details may change in any version, with the goal of improving error messages.

Source

A hyper::Error may be caused by another error. To aid in debugging, those are exposed in Error::source() as erased types. While it is possible to check the exact type of the sources, they can not be depended on. They may come from private internal dependencies, and are subject to change at any moment.

Implementations

impl Error

pub fn is_parse(&self) -> bool

Returns true if this was an HTTP parse error.

pub fn is_parse_status(&self) -> bool

Returns true if this was an HTTP parse error caused by an invalid response status code or reason phrase.

pub fn is_user(&self) -> bool

Returns true if this error was caused by user code.

pub fn is_canceled(&self) -> bool

Returns true if this was about a Request that was canceled.

pub fn is_closed(&self) -> bool

Returns true if a sender’s channel is closed.

pub fn is_incomplete_message(&self) -> bool

Returns true if the connection closed before a message could complete.

pub fn is_body_write_aborted(&self) -> bool

Returns true if the body write was aborted.

pub fn is_timeout(&self) -> bool

Returns true if the error was caused by a timeout.

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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
