Struct h2::Error

pub struct Error { /* fields omitted */ }

Represents HTTP/2.0 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 the 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

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, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Reason> for Error

fn from(src: Reason) -> Error

Performs the conversion.
