Implementations§

Source§

impl WebSocketError

Source

pub fn is_protocol_error(&self) -> bool

Available on non-WebAssembly only.

Returns true if this is a protocol-level error (RFC 6455 violation).

Source

pub fn is_handshake_error(&self) -> bool

Available on non-WebAssembly only.

Returns true if this is a handshake error.

Source

pub fn is_closed(&self) -> bool

Returns true if the connection is closed.

Source

pub fn is_data_error(&self) -> bool

Available on non-WebAssembly only.

Returns true if this is a data validation error (invalid UTF-8 or size limit).

Source

pub fn is_io_error(&self) -> bool

Available on non-WebAssembly only.

Returns true if this wraps an I/O error.

Source

pub fn as_io_error(&self) -> Option<&Error>

Available on non-WebAssembly only.

Returns the underlying I/O error, if any.
