Enum websocket_server::Message
[−]
[src]
pub enum Message { Text(String), Binary(Vec<u8>), Close(Option<CloseData>), Ping(Vec<u8>), Pong(Vec<u8>), }
Represents an owned WebSocket message.
OwnedMessage
s are generated when the user receives a message (since the data
has to be copied out of the network buffer anyway).
If you would like to create a message out of borrowed data to use for sending
please use the Message
struct (which contains a Cow
).
Note that OwnedMessage
can Message
can be converted into each other.
Variants
Text(String)
A message containing UTF-8 text data
Binary(Vec<u8>)
A message containing binary data
Close(Option<CloseData>)
A message which indicates closure of the WebSocket connection. This message may or may not contain data.
Ping(Vec<u8>)
A ping message - should be responded to with a pong message. Usually the pong message will be sent with the same data as the received ping message.
Pong(Vec<u8>)
A pong message, sent in response to a Ping message, usually containing the same data as the received ping message.
Methods
impl OwnedMessage
[src]
fn is_close(&self) -> bool
Checks if this message is a close message.
assert!(OwnedMessage::Close(None).is_close());
fn is_control(&self) -> bool
Checks if this message is a control message.
Control messages are either Close
, Ping
, or Pong
.
assert!(OwnedMessage::Ping(vec![]).is_control()); assert!(OwnedMessage::Pong(vec![]).is_control()); assert!(OwnedMessage::Close(None).is_control());
fn is_data(&self) -> bool
Checks if this message is a data message.
Data messages are either Text
or Binary
.
assert!(OwnedMessage::Text("1337".to_string()).is_data()); assert!(OwnedMessage::Binary(vec![]).is_data());
fn is_ping(&self) -> bool
Checks if this message is a ping message.
Ping
messages can come at any time and usually generate a Pong
message
response.
assert!(OwnedMessage::Ping("ping".to_string().into_bytes()).is_ping());
fn is_pong(&self) -> bool
Checks if this message is a pong message.
Pong
messages are usually sent only in response to Ping
messages.
assert!(OwnedMessage::Pong("pong".to_string().into_bytes()).is_pong());
