Struct hyper::Error

source ·
pub struct Error { /* private fields */ }
Expand description

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

source

pub fn is_parse(&self) -> bool

Returns true if this was an HTTP parse error.

source

pub fn is_parse_too_large(&self) -> bool

Returns true if this was an HTTP parse error caused by a message that was too large.

source

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.

source

pub fn is_user(&self) -> bool

Returns true if this error was caused by user code.

source

pub fn is_canceled(&self) -> bool

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

source

pub fn is_closed(&self) -> bool

Returns true if a sender’s channel is closed.

source

pub fn is_incomplete_message(&self) -> bool

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

source

pub fn is_body_write_aborted(&self) -> bool

Returns true if the body write was aborted.

source
