Enum Error 

pub enum Error {
    Protocol(Violation),
    Validation(ValidationError),
    Parse(ParseError),
    Io(Error),
    HandshakeTimeout,
    WriteTimeout,
}

Anything that can go wrong while running a session.

Variants

Protocol(Violation)

The wire contract was broken.

Validation(ValidationError)

A snapshot failed validation before it was sent.

Parse(ParseError)

An incoming message could not be parsed.

Io(Error)

The transport failed.

HandshakeTimeout

The driver did not answer the handshake in time.

WriteTimeout

The driver did not read a frame within the write deadline.

Distinct from Error::Io so a caller can tell a slow driver — drop the frame, keep rendering — from a snapshot refused as invalid, which will be refused again for the same tree. Part of a length-prefixed frame may already be on the wire, so the session is over, not delayed.

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<ParseError> for Error

fn from(inner: ParseError) -> Self

Converts to this type from the input type.

impl From<ValidationError> for Error

fn from(inner: ValidationError) -> Self

Converts to this type from the input type.

impl From<Violation> for Error

fn from(inner: Violation) -> Self

Converts to this type from the input type.
