    Closed,
    PeerClosed,
    TruncatedFrame,
    Io(ErrorKind),
    Timeout,
    InvalidData,
    InvalidOptions,

}

Transport/router failure, independent of application response errors.

Variants

Closed

The shared connection was explicitly closed or its last owner dropped.

PeerClosed

EOF while idle, before the expected terminal response.

TruncatedFrame

EOF inside a frame, distinct from a clean byte-stream EOF.

Io(ErrorKind)

An OS-level read, write, or connect failed.

Timeout

Total setup or per-attempt local wait expired.

InvalidData

Malformed framing or envelope.

InvalidOptions

Invalid local range, limits, or options.

Capacity

Byte, item, or in-flight capacity is unavailable.

IdRangeExhausted

All IDs in the negotiated range are reserved or retired.

StreamClosed

An explicit ID has no live send permission on this connection.

UnsupportedOperation

A typed operation is unavailable on this protocol/generation.

Encode

Native serialization failed without submitting a request.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ErrorKind

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Eq for ErrorKind

impl Error for ErrorKind

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 PartialEq for ErrorKind

fn eq(&self, other: &ErrorKind) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
