Enum rocket_ws::Message

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

A WebSocket message.

A value of this type is typically constructed by calling .into() on a supported message type. This includes strings via &str and String and bytes via &[u8] and Vec<u8>:

#[get("/echo")]
fn echo_stream(ws: ws::WebSocket) -> ws::Stream!['static] {
    ws::Stream! { ws =>
        yield "Hello".into();
        yield String::from("Hello").into();
        yield (&[1u8, 2, 3][..]).into();
        yield vec![1u8, 2, 3].into();
    }
}

Other kinds of messages can be constructed directly:

#[get("/echo")]
fn echo_stream(ws: ws::WebSocket) -> ws::Stream!['static] {
    ws::Stream! { ws =>
        yield ws::Message::Ping(vec![b'h', b'i'])
    }
}

An enum representing the various forms of 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

Pong(Vec<u8>)

A pong message with the specified payload

The payload here must have a length less than 125 bytes

Close(Option<CloseFrame<'static>>)

A close message with the optional close frame.

Frame(Frame)

Raw frame. Note, that you’re not going to get this value while reading the message.

Implementations

impl Message

pub fn text<S>(string: S) -> Message

where S: Into<String>,

Create a new text WebSocket message from a stringable.

pub fn binary<B>(bin: B) -> Message

where B: Into<Vec<u8>>,

Create a new binary WebSocket message by converting to Vec<u8>.

pub fn is_text(&self) -> bool

Indicates whether a message is a text message.

pub fn is_binary(&self) -> bool

Indicates whether a message is a binary message.

pub fn is_ping(&self) -> bool

Indicates whether a message is a ping message.

pub fn is_pong(&self) -> bool

Indicates whether a message is a pong message.

pub fn is_close(&self) -> bool

Indicates whether a message is a close message.

pub fn len(&self) -> usize

Get the length of the WebSocket message.

pub fn is_empty(&self) -> bool

Returns true if the WebSocket message has no content. For example, if the other side of the connection sent an empty string.

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

Consume the WebSocket and return it as binary data.

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

Attempt to consume the WebSocket message and convert it to a String.

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.

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl Display for Message

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

Formats the value using the given formatter.

impl<'b> From<&'b [u8]> for Message

fn from(data: &'b [u8]) -> Message

Converts to this type from the input type.

impl<'s> From<&'s str> for Message

fn from(string: &'s str) -> Message

Converts to this type from the input type.

impl From<Message> for Vec<u8>

fn from(message: Message) -> Vec<u8>

Converts to this type from the input type.

impl From<String> for Message

fn from(string: String) -> Message

Converts to this type from the input type.

impl From<Vec<u8>> for Message

fn from(data: Vec<u8>) -> Message

Converts to this type from the input type.

impl PartialEq for Message

fn eq(&self, other: &Message) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sink<Message> for DuplexStream

type Error = Error

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: Message) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.

impl TryFrom<Message> for String

type Error = Error

The type returned in the event of a conversion error.

fn try_from( value: Message, ) -> Result<String, <String as TryFrom<Message>>::Error>
