Enum Error 

#[non_exhaustive]
pub enum Error {
    SessionClosed,
    GoAway(ErrorCode),
    StreamReset(u32),
    TooManyStreams(usize),
    Timeout,
    Protocol(&'static str),
    Io(Error),
}

Top-level error type.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SessionClosed

The session is closed and no further operations can be performed.

GoAway(ErrorCode)

The remote peer sent a GoAway frame and is no longer accepting new streams.

StreamReset(u32)

The peer reset the stream.

TooManyStreams(usize)

Config::max_streams would be exceeded.

Timeout

An operation timed out.

Protocol(&'static str)

Wire-format violation while decoding a frame.

Io(Error)

Underlying I/O failure.

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

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.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.
