Enum tokio_websockets::upgrade::Error

#[non_exhaustive]
pub enum Error {
    MissingHeader(&'static str),
    UpgradeNotWebSocket,
    ConnectionNotUpgrade,
    UnsupportedWebSocketVersion,
    Parsing(Error),
    DidNotSwitchProtocols(u16),
    WrongWebSocketAccept,
}

Available on crate features client or server only.

Errors that occur during the HTTP upgrade handshake between client and server.

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.

MissingHeader(&'static str)

Header required in the request or response is not present.

UpgradeNotWebSocket

Upgrade header sent by the client does not match “websocket”.

ConnectionNotUpgrade

Connection header sent by the client does not contain “Upgrade”.

UnsupportedWebSocketVersion

Sec-WebSocket-Version header sent by the client is not supported by the server.

Parsing(Error)

Failed to parse client request or server response.

DidNotSwitchProtocols(u16)

Server did not return a HTTP Switching Protocols response.

WrongWebSocketAccept

Server returned a Sec-WebSocket-Accept that is not compatible with the Sec-WebSocket-Key sent by the client.

Trait Implementations

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

Formats the value using the given formatter.

impl Display for Error

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

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(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error
