Enum yamux::ConnectionError

#[non_exhaustive]
pub enum ConnectionError {
    Io(Error),
    Decode(FrameDecodeError),
    NoMoreStreamIds,
    Closed,
    TooManyStreams,
}

The various error cases a connection may encounter.

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.

Io(Error)

An underlying I/O error occured.

Decode(FrameDecodeError)

Decoding a Yamux message frame failed.

NoMoreStreamIds

The whole range of stream IDs has been used up.

Closed

An operation fails because the connection is closed.

TooManyStreams

Too many streams are open, so no further ones can be opened at this time.

Trait Implementations

impl Debug for ConnectionError

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for ConnectionError

fn fmt(&self, __formatter: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for ConnectionError

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 1.41.0:

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
