Struct rouille::websocket::Websocket

pub struct Websocket { /* fields omitted */ }

A successful websocket. An open channel of communication. Implements Read and Write.

Methods

impl Websocket

pub fn send_text(&mut self, data: &str) -> Result<(), SendError>

Sends text data over the websocket.

Returns an error if the message didn't send correctly or if the connection is closed.

If the client is in javascript, the message will contain a string.

pub fn send_binary(&mut self, data: &[u8]) -> Result<(), SendError>

Sends binary data over the websocket.

Returns an error if the message didn't send correctly or if the connection is closed.

If the client is in javascript, the message will contain a blob or an arraybuffer.

pub fn is_closed(&self) -> bool

Returns true if the websocket has been closed by either the client (voluntarily or not) or by the server (if the websocket protocol was violated).
