Struct Error

pub struct Error { /* private fields */ }

Represents HTTP/2 operation errors.

Error covers error cases raised by protocol errors caused by the peer, I/O (transport) errors, and errors caused by the user of the library.

If the error was caused by the remote peer, then it will contain a Reason which can be obtained with the reason function.

Implementations

impl Error

pub fn reason(&self) -> Option<Reason>

If the error was caused by the remote peer, the error reason.

This is either an error received by the peer or caused by an invalid action taken by the peer (i.e. a protocol error).

pub fn is_io(&self) -> bool

Returns true if the error is an io::Error

pub fn get_io(&self) -> Option<&Error>

Returns the error if the error is an io::Error

pub fn into_io(self) -> Option<Error>

Returns the error if the error is an io::Error

pub fn is_go_away(&self) -> bool

Returns true if the error is from a GOAWAY.

pub fn is_reset(&self) -> bool

Returns true if the error is from a RST_STREAM.

pub fn is_remote(&self) -> bool

Returns true if the error was received in a frame from the remote.

Such as from a received RST_STREAM or GOAWAY frame.

pub fn is_library(&self) -> bool

Returns true if the error was created by h2.

Such as noticing some protocol error and sending a GOAWAY or RST_STREAM.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
