Enum Message

Source
pub enum Message {
    Text(String),
    Binary(Vec<u8>),
    Ping(Vec<u8>),
    Pong(Vec<u8>),
    Close(Option<CloseFrame<'static>>),
}
Expand description

A WebSocket message.

Variants§

§

Text(String)

A text WebSocket message

§

Binary(Vec<u8>)

A binary WebSocket message

§

Ping(Vec<u8>)

A ping message with the specified payload

The payload here must have a length less than 125 bytes.

Ping messages will be automatically responded to by the server, so you do not have to worry about dealing with them yourself.

§

Pong(Vec<u8>)

A pong message with the specified payload

The payload here must have a length less than 125 bytes.

Pong messages will be automatically sent to the client if a ping message is received, so you do not have to worry about constructing them yourself unless you want to implement a unidirectional heartbeat.

§

Close(Option<CloseFrame<'static>>)

A close message with the optional close frame.

Implementations§

Source§

impl Message

Source

pub fn into_data(self) -> Vec<u8>

Consume the WebSocket and return it as binary data.

Source

pub fn into_text(self) -> Result<String, Error>

Source

pub fn to_text(&self) -> Result<&str, Error>

Attempt to get a &str from the WebSocket message, this will try to convert binary data to utf8.
