Enum ws_stream_tungstenite::WsErr

#[non_exhaustive]pub enum WsErr {
    Tungstenite {
        source: Error,
    },
    Io {
        source: Error,
    },
    Protocol,
    ReceivedText,
    Closed,
}

The error type for errors happening in ws_stream_tungstenite.

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.

Tungstenite

A tungstenite error.

Fields of Tungstenite

source: Error

The underlying error.

Io

An error from the underlying connection.

Fields of Io

source: Error

The underlying error.

Protocol

A websocket protocol error. On read it means the remote didn't respect the websocket protocol. On write this means there's a bug in ws_stream_tungstenite and it will panic.

ReceivedText

We received a websocket text message. As we are about turning the websocket connection into a bytestream, this is probably unintended, and thus unsupported.

Closed

Trying to work with an connection that is closed. Only happens on writing. On reading poll_read will just return None.

impl Error for WsErr

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

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

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